+ * "AVS" is the name of a firmware developed at Broadcom. It derives
+ * its name from the technique called "Adaptive Voltage Scaling".
+ * Adaptive voltage scaling was the original purpose of this firmware.
+ * The AVS firmware still supports "AVS mode", where all it does is
+ * adaptive voltage scaling. However, on some newer Broadcom SoCs, the
+ * AVS Firmware, despite its unchanged name, also supports DFS mode and
+ * DVFS mode.
+ *
+ * In the context of this document and the related driver, "AVS" by
+ * itself always means the Broadcom firmware and never refers to the
+ * technique called "Adaptive Voltage Scaling".
+ *
+ * The Broadcom STB AVS CPUfreq driver provides voltage and frequency
+ * scaling on Broadcom SoCs using AVS firmware with support for DFS and
+ * DVFS. The AVS firmware is running on its own co-processor. The
+ * driver supports both uniprocessor (UP) and symmetric multiprocessor
+ * (SMP) systems which share clock and voltage across all CPUs.
+ *
+ * Actual voltage and frequency scaling is done solely by the AVS
+ * firmware. This driver does not change frequency or voltage itself.
+ * It provides a standard CPUfreq interface to the rest of the kernel
+ * and to userland. It interfaces with the AVS firmware to effect the
+ * requested changes and to report back the current system status in a
+ * way that is expected by existing tools.

+	 * is not defined. TI recommends to check that RD_ACTIVE and WR_ACTIVE

+	 * will occur.
+	 * The problem is that if the channel is active, then device activity
+	 * can result in DMA activity starting between reading those as both
+	 * clear and the write to DMA_CCR to clear the enable bit hitting the

+ *
+ * Parse a series of EFI Device Path nodes at @node and find the corresponding
+ * device.  If the device was found, its reference count is incremented and a
+ * pointer to it is returned.  The caller needs to drop the reference with
+ * put_device() after use.  The @node pointer is updated to point to the
+ * location immediately after the "End of Hardware Device Path" node.
+ *
+ * If another Device Path instance follows, @len is decremented by the number
+ * of bytes consumed.  Otherwise @len is set to %0.
+ *
+ * If a Device Path node is malformed or its corresponding device is not found,
+ * @node is updated to point to this offending node and an ERR_PTR is returned.
+ *
+ * If @len is initially %0, the function returns %NULL.  Thus, to iterate over
+ * all instances in a path, the following idiom may be used:
+ *
+ *	while (!IS_ERR_OR_NULL(dev = efi_get_device_by_path(&node, &len))) {
+ *		// do something with dev
+ *		put_device(dev);
+ *	}
+ *	if (IS_ERR(dev))
+ *		// report error
+ *
+ * Devices can only be found if they're already instantiated. Most buses
+ * instantiate devices in the "subsys" initcall level, hence the earliest
+ * initcall level in which this function should be called is "fs".
+ *
+ * Returns the device on success or
+ *	%ERR_PTR(-ENODEV) if no device was found,
+ *	%ERR_PTR(-EINVAL) if a node is malformed or exceeds @len,
+ *	%ERR_PTR(-ENOTSUPP) if support for a node type is not yet implemented.

+	help
+	  IVC (Inter-VM Communication) protocol is part of the IPC
+	  (Inter Processor Communication) framework on Tegra. It maintains the
+	  data and the different commuication channels in SysRAM or RAM and
+	  keeps the content is synchronization between host CPU and remote

+config TEGRA_BPMP
+	bool "Tegra BPMP driver"
+	depends on ARCH_TEGRA && TEGRA_HSP_MBOX && TEGRA_IVC
+	help
+	  BPMP (Boot and Power Management Processor) is designed to off-loading
+	  the PM functions which include clock/DVFS/thermal/power from the CPU.
+	  It needs HSP as the HW synchronization and notification module and
+	  IVC module as the message communication protocol.
+
+	  This driver manages the IPC interface between host CPU and the
+	  firmware running on BPMP.

-/**
- * struct sx150x_platform_data - config data for SX150x driver
- * @gpio_base: The index number of the first GPIO assigned to this
- *             GPIO expander.  The expander will create a block of
- *             consecutively numbered gpios beginning at the given base,
- *             with the size of the block depending on the model of the
- *             expander chip.
- * @oscio_is_gpo: If set to true, the driver will configure OSCIO as a GPO
- *                instead of as an oscillator, increasing the size of the
- *                GP(I)O pool created by this expander by one.  The
- *                output-only GPO pin will be added at the end of the block.
- * @io_pullup_ena: A bit-mask which enables or disables the pull-up resistor
- *                 for each IO line in the expander.  Setting the bit at
- *                 position n will enable the pull-up for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_pulldn_ena: A bit-mask which enables-or disables the pull-down
- *                 resistor for each IO line in the expander. Setting the
- *                 bit at position n will enable the pull-down for the IO at
- *                 the corresponding offset.  For chips with fewer than
- *                 16 IO pins, high-end bits are ignored.
- * @io_polarity: A bit-mask which enables polarity inversion for each IO line
- *               in the expander.  Setting the bit at position n inverts
- *               the polarity of that IO line, while clearing it results
- *               in normal polarity. For chips with fewer than 16 IO pins,
- *               high-end bits are ignored.
- * @irq_summary: The 'summary IRQ' line to which the GPIO expander's INT line
- *               is connected, via which it reports interrupt events
- *               across all GPIO lines.  This must be a real,
- *               pre-existing IRQ line.
- *               Setting this value < 0 disables the irq_chip functionality
- *               of the driver.
- * @irq_base: The first 'virtual IRQ' line at which our block of GPIO-based
- *            IRQ lines will appear.  Similarly to gpio_base, the expander
- *            will create a block of irqs beginning at this number.
- *            This value is ignored if irq_summary is < 0.
- * @reset_during_probe: If set to true, the driver will trigger a full
- *                      reset of the chip at the beginning of the probe
- *                      in order to place it in a known state.

- * These utility functions solve the common problem of locating and setting

- * REGISTER N-1 [ f e d c b a 9 8 ]
- *          N   [ 7 6 5 4 3 2 1 0 ]
- *
- * For multi-bit configurations, the pattern gets wider:

- *          N-2 [ b b a a 9 9 8 8 ]

- * Given the address of the starting register 'N', the index of the gpio
- * whose configuration we seek to change, and the width in bits of that
- * configuration, these functions allow us to locate the correct
- * register and mask the correct bits.

+/**
+ * DOC: explicit fencing properties
+ *
+ * Explicit fencing allows userspace to control the buffer synchronization
+ * between devices. A Fence or a group of fences are transfered to/from
+ * userspace using Sync File fds and there are two DRM properties for that.
+ * IN_FENCE_FD on each DRM Plane to send fences to the kernel and
+ * OUT_FENCE_PTR on each DRM CRTC to receive fences from the kernel.
+ *
+ * As a contrast, with implicit fencing the kernel keeps track of any
+ * ongoing rendering, and automatically ensures that the atomic update waits
+ * for any pending rendering to complete. For shared buffers represented with
+ * a struct &dma_buf this is tracked in &reservation_object structures.
+ * Implicit syncing is how Linux traditionally worked (e.g. DRI2/3 on X.org),
+ * whereas explicit fencing is what Android wants.
+ *
+ * "IN_FENCE_FD”:
+ *	Use this property to pass a fence that DRM should wait on before
+ *	proceeding with the Atomic Commit request and show the framebuffer for
+ *	the plane on the screen. The fence can be either a normal fence or a
+ *	merged one, the sync_file framework will handle both cases and use a
+ *	fence_array if a merged fence is received. Passing -1 here means no
+ *	fences to wait on.
+ *
+ *	If the Atomic Commit request has the DRM_MODE_ATOMIC_TEST_ONLY flag
+ *	it will only check if the Sync File is a valid one.
+ *
+ *	On the driver side the fence is stored on the @fence parameter of
+ *	struct &drm_plane_state. Drivers which also support implicit fencing
+ *	should set the implicit fence using drm_atomic_set_fence_for_plane(),
+ *	to make sure there's consistent behaviour between drivers in precedence
+ *	of implicit vs. explicit fencing.
+ *
+ * "OUT_FENCE_PTR”:
+ *	Use this property to pass a file descriptor pointer to DRM. Once the
+ *	Atomic Commit request call returns OUT_FENCE_PTR will be filled with
+ *	the file descriptor number of a Sync File. This Sync File contains the
+ *	CRTC fence that will be signaled when all framebuffers present on the
+ *	Atomic Commit * request for that given CRTC are scanned out on the
+ *	screen.
+ *
+ *	The Atomic Commit request fails if a invalid pointer is passed. If the
+ *	Atomic Commit request fails for any other reason the out fence fd
+ *	returned will be -1. On a Atomic Commit with the
+ *	DRM_MODE_ATOMIC_TEST_ONLY flag the out fence will also be set to -1.
+ *
+ *	Note that out-fences don't have a special interface to drivers and are
+ *	internally represented by a struct &drm_pending_vblank_event in struct
+ *	&drm_crtc_state, which is also used by the nonblocking atomic commit
+ *	helpers and for the DRM event handling for existing userspace.

+ *
+ * EDID:
+ * 	Blob property which contains the current EDID read from the sink. This
+ * 	is useful to parse sink identification information like vendor, model
+ * 	and serial. Drivers should update this property by calling
+ * 	drm_mode_connector_update_edid_property(), usually after having parsed
+ * 	the EDID using drm_add_edid_modes(). Userspace cannot change this
+ * 	property.
+ * DPMS:
+ * 	Legacy property for setting the power state of the connector. For atomic
+ * 	drivers this is only provided for backwards compatibility with existing
+ * 	drivers, it remaps to controlling the "ACTIVE" property on the CRTC the
+ * 	connector is linked to. Drivers should never set this property directly,
+ * 	it is handled by the DRM core by calling the ->dpms() callback in
+ * 	&drm_connector_funcs. Atomic drivers should implement this hook using
+ * 	drm_atomic_helper_connector_dpms(). This is the only property standard
+ * 	connector property that userspace can change.
+ * PATH:
+ * 	Connector path property to identify how this sink is physically
+ * 	connected. Used by DP MST. This should be set by calling
+ * 	drm_mode_connector_set_path_property(), in the case of DP MST with the
+ * 	path property the MST manager created. Userspace cannot change this
+ * 	property.
+ * TILE:
+ * 	Connector tile group property to indicate how a set of DRM connector
+ * 	compose together into one logical screen. This is used by both high-res
+ * 	external screens (often only using a single cable, but exposing multiple
+ * 	DP MST sinks), or high-res integrated panels (like dual-link DSI) which
+ * 	are not gen-locked. Note that for tiled panels which are genlocked, like
+ * 	dual-link LVDS or dual-link DSI, the driver should try to not expose the
+ * 	tiling and virtualize both &drm_crtc and &drm_plane if needed. Drivers
+ * 	should update this value using drm_mode_connector_set_tile_property().
+ * 	Userspace cannot change this property.

+/**
+ * DOC: CRC ABI
+ *
+ * DRM device drivers can provide to userspace CRC information of each frame as
+ * it reached a given hardware component (a "source").
+ *
+ * Userspace can control generation of CRCs in a given CRTC by writing to the
+ * file dri/0/crtc-N/crc/control in debugfs, with N being the index of the CRTC.
+ * Accepted values are source names (which are driver-specific) and the "auto"
+ * keyword, which will let the driver select a default source of frame CRCs
+ * for this CRTC.
+ *
+ * Once frame CRC generation is enabled, userspace can capture them by reading
+ * the dri/0/crtc-N/crc/data file. Each line in that file contains the frame
+ * number in the first field and then a number of unsigned integer fields
+ * containing the CRC data. Fields are separated by a single space and the number
+ * of CRC fields is source-specific.
+ *
+ * Note that though in some cases the CRC is computed in a specified way and on
+ * the frame contents as supplied by userspace (eDP 1.3), in general the CRC
+ * computation is performed in an unspecified way and on frame contents that have
+ * been already processed in also an unspecified way and thus userspace cannot
+ * rely on being able to generate matching CRC values for the frame contents that
+ * it submits. In this general case, the maximum userspace can do is to compare
+ * the reported CRCs of frames that should have the same contents.

+ * DOC: overview
+ *
+ * The KMS API doesn't standardize backing storage object creation and leaves it
+ * to driver-specific ioctls. Furthermore actually creating a buffer object even
+ * for GEM-based drivers is done through a driver-specific ioctl - GEM only has
+ * a common userspace interface for sharing and destroying objects. While not an
+ * issue for full-fledged graphics stacks that include device-specific userspace
+ * components (in libdrm for instance), this limit makes DRM-based early boot
+ * graphics unnecessarily complex.
+ *
+ * Dumb objects partly alleviate the problem by providing a standard API to
+ * create dumb buffers suitable for scanout, which can then be used to create
+ * KMS frame buffers.
+ *
+ * To support dumb objects drivers must implement the dumb_create,
+ * dumb_destroy and dumb_map_offset operations from struct &drm_driver. See
+ * there for further details.
+ *
+ * Note that dumb objects may not be used for gpu acceleration, as has been
+ * attempted on some ARM embedded platforms. Such drivers really must have
+ * a hardware-specific ioctl to allocate suitable buffer objects.

-	 * wrong engine as being busy (but we guarantee that the result
-	 * is at least self-consistent).
-	 *
-	 * As we use SLAB_DESTROY_BY_RCU, the request may be reallocated
-	 * whilst we are inspecting it, even under the RCU read lock as we are.
-	 * This means that there is a small window for the engine and/or the
-	 * seqno to have been overwritten. The seqno will always be in the
-	 * future compared to the intended, and so we know that if that
-	 * seqno is idle (on whatever engine) our request is idle and the
-	 * return 0 above is correct.
-	 *
-	 * The issue is that if the engine is switched, it is just as likely
-	 * to report that it is busy (but since the switch happened, we know
-	 * the request should be idle). So there is a small chance that a busy
-	 * result is actually the wrong engine.
-	 *
-	 * So why don't we care?
-	 *
-	 * For starters, the busy ioctl is a heuristic that is by definition
-	 * racy. Even with perfect serialisation in the driver, the hardware
-	 * state is constantly advancing - the state we report to the user
-	 * is stale.
-	 *
-	 * The critical information for the busy-ioctl is whether the object
-	 * is idle as userspace relies on that to detect whether its next
-	 * access will stall, or if it has missed submitting commands to
-	 * the hardware allowing the GPU to stall. We never generate a
-	 * false-positive for idleness, thus busy-ioctl is reliable at the
-	 * most fundamental level, and we maintain the guarantee that a
-	 * busy object left to itself will eventually become idle (and stay
-	 * idle!).
+	/* We have to check the current hw status of the fence as the uABI
+	 * guarantees forward progress. We could rely on the idle worker
+	 * to eventually flush us, but to minimise latency just ask the
+	 * hardware.
 	 *
-	 * We allow ourselves the leeway of potentially misreporting the busy

-/**
- * DOC: DPIO
- *
- * VLV, CHV and BXT have slightly peculiar display PHYs for driving DP/HDMI
- * ports. DPIO is the name given to such a display PHY. These PHYs
- * don't follow the standard programming model using direct MMIO
- * registers, and instead their registers must be accessed trough IOSF
- * sideband. VLV has one such PHY for driving ports B and C, and CHV
- * adds another PHY for driving port D. Each PHY responds to specific
- * IOSF-SB port.
- *
- * Each display PHY is made up of one or two channels. Each channel
- * houses a common lane part which contains the PLL and other common
- * logic. CH0 common lane also contains the IOSF-SB logic for the
- * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
- * must be running when any DPIO registers are accessed.
- *
- * In addition to having their own registers, the PHYs are also
- * controlled through some dedicated signals from the display
- * controller. These include PLL reference clock enable, PLL enable,
- * and CRI clock selection, for example.
- *
- * Eeach channel also has two splines (also called data lanes), and
- * each spline is made up of one Physical Access Coding Sub-Layer
- * (PCS) block and two TX lanes. So each channel has two PCS blocks
- * and four TX lanes. The TX lanes are used as DP lanes or TMDS
- * data/clock pairs depending on the output type.
- *
- * Additionally the PHY also contains an AUX lane with AUX blocks
- * for each channel. This is used for DP AUX communication, but
- * this fact isn't really relevant for the driver since AUX is
- * controlled from the display controller side. No DPIO registers
- * need to be accessed during AUX communication,
- *
- * Generally on VLV/CHV the common lane corresponds to the pipe and
- * the spline (PCS/TX) corresponds to the port.
- *
- * For dual channel PHY (VLV/CHV):
- *
- *  pipe A == CMN/PLL/REF CH0
- *
- *  pipe B == CMN/PLL/REF CH1
- *
- *  port B == PCS/TX CH0
- *
- *  port C == PCS/TX CH1
- *
- * This is especially important when we cross the streams
- * ie. drive port B with pipe B, or port C with pipe A.
- *
- * For single channel PHY (CHV):
- *
- *  pipe C == CMN/PLL/REF CH0
- *
- *  port D == PCS/TX CH0
- *
- * On BXT the entire PHY channel corresponds to the port. That means
- * the PLL is also now associated with the port rather than the pipe,
- * and so the clock needs to be routed to the appropriate transcoder.
- * Port A PLL is directly connected to transcoder EDP and port B/C
- * PLLs can be routed to any transcoder A/B/C.
- *
- * Note: DDI0 is digital port B, DD1 is digital port C, and DDI2 is
- * digital port D (CHV) or port A (BXT). ::

 #include "intel_drv.h"
 
+/**
+ * DOC: DPIO
+ *
+ * VLV, CHV and BXT have slightly peculiar display PHYs for driving DP/HDMI
+ * ports. DPIO is the name given to such a display PHY. These PHYs
+ * don't follow the standard programming model using direct MMIO
+ * registers, and instead their registers must be accessed trough IOSF
+ * sideband. VLV has one such PHY for driving ports B and C, and CHV
+ * adds another PHY for driving port D. Each PHY responds to specific
+ * IOSF-SB port.
+ *
+ * Each display PHY is made up of one or two channels. Each channel
+ * houses a common lane part which contains the PLL and other common
+ * logic. CH0 common lane also contains the IOSF-SB logic for the
+ * Common Register Interface (CRI) ie. the DPIO registers. CRI clock
+ * must be running when any DPIO registers are accessed.
+ *
+ * In addition to having their own registers, the PHYs are also
+ * controlled through some dedicated signals from the display
+ * controller. These include PLL reference clock enable, PLL enable,
+ * and CRI clock selection, for example.
+ *
+ * Eeach channel also has two splines (also called data lanes), and
+ * each spline is made up of one Physical Access Coding Sub-Layer
+ * (PCS) block and two TX lanes. So each channel has two PCS blocks
+ * and four TX lanes. The TX lanes are used as DP lanes or TMDS
+ * data/clock pairs depending on the output type.
+ *
+ * Additionally the PHY also contains an AUX lane with AUX blocks
+ * for each channel. This is used for DP AUX communication, but
+ * this fact isn't really relevant for the driver since AUX is
+ * controlled from the display controller side. No DPIO registers
+ * need to be accessed during AUX communication,
+ *
+ * Generally on VLV/CHV the common lane corresponds to the pipe and
+ * the spline (PCS/TX) corresponds to the port.
+ *
+ * For dual channel PHY (VLV/CHV):
+ *
+ *  pipe A == CMN/PLL/REF CH0
+ *
+ *  pipe B == CMN/PLL/REF CH1
+ *
+ *  port B == PCS/TX CH0
+ *
+ *  port C == PCS/TX CH1
+ *
+ * This is especially important when we cross the streams
+ * ie. drive port B with pipe B, or port C with pipe A.
+ *
+ * For single channel PHY (CHV):
+ *
+ *  pipe C == CMN/PLL/REF CH0
+ *
+ *  port D == PCS/TX CH0
+ *
+ * On BXT the entire PHY channel corresponds to the port. That means
+ * the PLL is also now associated with the port rather than the pipe,
+ * and so the clock needs to be routed to the appropriate transcoder.
+ * Port A PLL is directly connected to transcoder EDP and port B/C
+ * PLLs can be routed to any transcoder A/B/C.
+ *
+ * Note: DDI0 is digital port B, DD1 is digital port C, and DDI2 is
+ * digital port D (CHV) or port A (BXT). ::

+ * Below state structure is used for coordination of retrieval of GuC firmware
+ * logs. Separate state is maintained for each log buffer type.
+ * read_ptr points to the location where i915 read last in log buffer and
+ * is read only for GuC firmware. write_ptr is incremented by GuC with number
+ * of bytes written for each log entry and is read only for i915.
+ * When any type of log buffer becomes half full, GuC sends a flush interrupt.
+ * GuC firmware expects that while it is writing to 2nd half of the buffer,
+ * first half would get consumed by Host and then get a flush completed
+ * acknowledgment from Host, so that it does not end up doing any overwrite
+ * causing loss of logs. So when buffer gets half filled & i915 has requested
+ * for interrupt, GuC will set flush_to_file field, set the sampled_write_ptr
+ * to the value of write_ptr and raise the interrupt.
+ * On receiving the interrupt i915 should read the buffer, clear flush_to_file
+ * field and also update read_ptr with the value of sample_write_ptr, before
+ * sending an acknowledgment to GuC. marker & version fields are for internal
+ * usage of GuC and opaque to i915. buffer_full_cnt field is incremented every
+ * time GuC detects the log buffer overflow.

-/* SMP - Shared Memory Pool
- *
- * These are shared between all the clients, where each plane in a
- * scanout buffer is a SMP client.  Ie. scanout of 3 plane I420 on
- * pipe VIG0 => 3 clients: VIG0_Y, VIG0_CB, VIG0_CR.
- *
- * Based on the size of the attached scanout buffer, a certain # of
- * blocks must be allocated to that client out of the shared pool.
- *
- * In some hw, some blocks are statically allocated for certain pipes
- * and CANNOT be re-allocated (eg: MMB0 and MMB1 both tied to RGB0).
- *
- * For each block that can be dynamically allocated, it can be either
- *     free:
- *     The block is free.
- *
- *     pending:
- *     The block is allocated to some client and not free.
- *
- *     configured:
- *     The block is allocated to some client, and assigned to that
- *     client in MDP5_SMP_ALLOC registers.
- *
- *     inuse:
- *     The block is being actively used by a client.
- *
- * The updates happen in the following steps:
- *
- *  1) mdp5_smp_request():
- *     When plane scanout is setup, calculate required number of
- *     blocks needed per client, and request. Blocks neither inuse nor
- *     configured nor pending by any other client are added to client's
- *     pending set.
- *     For shrinking, blocks in pending but not in configured can be freed
- *     directly, but those already in configured will be freed later by
- *     mdp5_smp_commit.
- *
- *  2) mdp5_smp_configure():
- *     As hw is programmed, before FLUSH, MDP5_SMP_ALLOC registers
- *     are configured for the union(pending, inuse)
- *     Current pending is copied to configured.
- *     It is assumed that mdp5_smp_request and mdp5_smp_configure not run
- *     concurrently for the same pipe.
- *
- *  3) mdp5_smp_commit():
- *     After next vblank, copy configured -> inuse.  Optionally update
- *     MDP5_SMP_ALLOC registers if there are newly unused blocks
- *
- *  4) mdp5_smp_release():
- *     Must be called after the pipe is disabled and no longer uses any SMB
- *

-/* This ugly bit of math is equivalent to DIV_ROUNDUP(size, X) where X is
- * the value I40E_MAX_DATA_PER_TXD_ALIGNED.  It is needed due to the fact
- * that 12K is not a power of 2 and division is expensive.  It is used to
- * approximate the number of descriptors used per linear buffer.  Note
- * that this will overestimate in some cases as it doesn't account for the
- * fact that we will add up to 4K - 1 in aligning the 12K buffer, however
- * the error should not impact things much as large buffers usually mean
- * we will use fewer descriptors then there are frags in an skb.
+/**
+ * i40e_txd_use_count  - estimate the number of descriptors needed for Tx
+ * @size: transmit request size in bytes
+ *
+ * Due to hardware alignment restrictions (4K alignment), we need to
+ * assume that we can have no more than 12K of data per descriptor, even
+ * though each descriptor can take up to 16K - 1 bytes of aligned memory.
+ * Thus, we need to divide by 12K. But division is slow! Instead,
+ * we decompose the operation into shifts and one relatively cheap
+ * multiply operation.
+ *
+ * To divide by 12K, we first divide by 4K, then divide by 3:
+ *     To divide by 4K, shift right by 12 bits
+ *     To divide by 3, multiply by 85, then divide by 256
+ *     (Divide by 256 is done by shifting right by 8 bits)
+ * Finally, we add one to round up. Because 256 isn't an exact multiple of
+ * 3, we'll underestimate near each multiple of 12K. This is actually more
+ * accurate as we have 4K - 1 of wiggle room that we can fit into the last
+ * segment.  For our purposes this is accurate out to 1M which is orders of
+ * magnitude greater than our largest possible GSO size.
+ *
+ * This would then be implemented as:
+ *     return (((size >> 12) * 85) >> 8) + 1;
+ *
+ * Since multiplication and division are commutative, we can reorder
+ * operations into:
+ *     return ((size * 85) >> 20) + 1;

+ * i40e_txd_use_count  - estimate the number of descriptors needed for Tx
+ * @size: transmit request size in bytes
+ *
+ * Due to hardware alignment restrictions (4K alignment), we need to
+ * assume that we can have no more than 12K of data per descriptor, even
+ * though each descriptor can take up to 16K - 1 bytes of aligned memory.
+ * Thus, we need to divide by 12K. But division is slow! Instead,
+ * we decompose the operation into shifts and one relatively cheap
+ * multiply operation.
+ *
+ * To divide by 12K, we first divide by 4K, then divide by 3:
+ *     To divide by 4K, shift right by 12 bits
+ *     To divide by 3, multiply by 85, then divide by 256
+ *     (Divide by 256 is done by shifting right by 8 bits)
+ * Finally, we add one to round up. Because 256 isn't an exact multiple of
+ * 3, we'll underestimate near each multiple of 12K. This is actually more
+ * accurate as we have 4K - 1 of wiggle room that we can fit into the last
+ * segment.  For our purposes this is accurate out to 1M which is orders of
+ * magnitude greater than our largest possible GSO size.
+ *
+ * This would then be implemented as:
+ *     return (((size >> 12) * 85) >> 8) + 1;
+ *
+ * Since multiplication and division are commutative, we can reorder
+ * operations into:

+ *
+ * NIC register I/O
+ *
+ **************************************************************************
+ *
+ * Notes on locking strategy for the Falcon architecture:
+ *
+ * Many CSRs are very wide and cannot be read or written atomically.
+ * Writes from the host are buffered by the Bus Interface Unit (BIU)
+ * up to 128 bits.  Whenever the host writes part of such a register,
+ * the BIU collects the written value and does not write to the
+ * underlying register until all 4 dwords have been written.  A
+ * similar buffering scheme applies to host access to the NIC's 64-bit
+ * SRAM.
+ *
+ * Writes to different CSRs and 64-bit SRAM words must be serialised,
+ * since interleaved access can result in lost writes.  We use
+ * ef4_nic::biu_lock for this.
+ *
+ * We also serialise reads from 128-bit CSRs and SRAM with the same
+ * spinlock.  This may not be necessary, but it doesn't really matter
+ * as there are no such reads on the fast path.
+ *
+ * The DMA descriptor pointers (RX_DESC_UPD and TX_DESC_UPD) are
+ * 128-bit but are special-cased in the BIU to avoid the need for
+ * locking in the host:
+ *
+ * - They are write-only.
+ * - The semantics of writing to these registers are such that
+ *   replacing the low 96 bits with zero does not affect functionality.
+ * - If the host writes to the last dword address of such a register
+ *   (i.e. the high 32 bits) the underlying register will always be
+ *   written.  If the collector and the current write together do not
+ *   provide values for all 128 bits of the register, the low 96 bits
+ *   will be written as zero.
+ * - If the host writes to the address of any other part of such a
+ *   register while the collector already holds values for some other
+ *   register, the write is discarded and the collector maintains its
+ *   current state.
+ *
+ * The EF10 architecture exposes very few registers to the host and
+ * most of them are only 32 bits wide.  The only exceptions are the MC
+ * doorbell register pair, which has its own latching, and
+ * TX_DESC_UPD, which works in a similar way to the Falcon
+ * architecture.

+	 * This affects the FC-NVME implementation in two ways:

+	 * 2) The FC-NVME implementation requires that delivery of
+	 *    ERSP completions are to go back to the nvme layer in order
+	 *    relative to the rsn, such that the sqhd value will always
+	 *    be "in order" for the nvme layer. As the nvme layer in
+	 *    linux doesn't care about sqhd, there's no need to return
+	 *    them in order.
+	 *
+	 * Additionally:
+	 * As the core nvme layer in linux currently does not look at
+	 * every field in the cqe - in cases where the FC transport must
+	 * fabricate a CQE, the following fields will not be set as they

  *
- * @resolve:	Node to resolve
+ * @overlay:	Pointer to devicetree overlay to relocate and resolve
  *
- * Perform dynamic Device Tree resolution against the live tree
- * to the given node to resolve. This depends on the live tree
- * having a __symbols__ node, and the resolve node the __fixups__ &
- * __local_fixups__ nodes (if needed).
- * The result of the operation is a resolve node that it's contents
- * are fit to be inserted or operate upon the live tree.
- * Returns 0 on success or a negative error value on error.
+ * Modify (relocate) values of local phandles in @overlay to a range that
+ * does not conflict with the live expanded devicetree.  Update references
+ * to the local phandles in @overlay.  Update (resolve) phandle references
+ * in @overlay that refer to the live expanded devicetree.
+ *
+ * Phandle values in the live tree are in the range of
+ * 1 .. live_tree_max_phandle().  The range of phandle values in the overlay
+ * also begin with at 1.  Adjust the phandle values in the overlay to begin
+ * at live_tree_max_phandle() + 1.  Update references to the phandles to
+ * the adjusted phandle values.
+ *
+ * The name of each property in the "__fixups__" node in the overlay matches
+ * the name of a symbol (a label) in the live tree.  The values of each
+ * property in the "__fixups__" node is a list of the property values in the
+ * overlay that need to be updated to contain the phandle reference
+ * corresponding to that symbol in the live tree.  Update the references in
+ * the overlay with the phandle values in the live tree.
+ *
+ * @overlay must be detached.
+ *
+ * Resolving and applying @overlay to the live expanded devicetree must be
+ * protected by a mechanism to ensure that multiple overlays are processed
+ * in a single threaded manner so that multiple overlays will not relocate
+ * phandles to overlapping ranges.  The mechanism to enforce this is not
+ * yet implemented.
+ *
+ * Return: %0 on success or a negative error value on error.

+	  The global utilities block controls power management, I/O device
+	  enabling, power-onreset(POR) configuration monitoring, alternate
+	  function selection for multiplexed signals,and clock control.
+	  This driver is to manage and access global utilities block.
+	  Initially only reading SVR and registering soc device are supported.
+	  Other guts accesses, such as reading RCW, should eventually be moved
+	  into this driver as well.

-Core:
-1) Get reviews
-2) Additional testing
-3) Ensure all desirable features present by adding more devices.
-   Major changes not expected except in response to comments
-
-Max1363 core:
-1) Possibly add sysfs exports of constant useful to userspace.
-Would be nice
-2) Support hardware generated interrupts
-3) Expand device set. Lots of other maxim adc's have very
-   similar interfaces.
-
-MXS LRADC driver:
-This is a classic MFD device as it combines the following subdevices
- - touchscreen controller (input subsystem related device)
- - general purpose ADC channels
- - battery voltage monitor (power subsystem related device)
- - die temperature monitor (thermal management)
-
-At least the battery voltage and die temperature feature is required in-kernel
-by a driver of the SoC's battery charging unit to avoid any damage to the
-silicon and the battery.
-
-TSL2561
-Would be nice
-1) Open question of userspace vs kernel space balance when
-converting to useful light measurements from device ones.
-2) Add sysfs elements necessary to allow device agnostic
-unit conversion.
-
-LIS3L02DQ core
-
-LIS3L02DQ ring
-
-KXSD9
-Currently minimal driver, would be nice to add:
-1) Support for all chip generated interrupts (events),
-basically get support up to level of lis3l02dq driver.
-
-Ring buffer core
-
-SCA3000
-Would be nice
-1) Testing on devices other than sca3000-e05
-
-Trigger core support
-1) Discussion of approach. Is it general enough?
-
-Ring Buffer:
-1) Discussion of approach.
-There are probably better ways of doing this. The
-intention is to allow for more than one software ring
-buffer implementation as different users will have
-different requirements.  This one suits mid range
-frequencies (100Hz - 4kHz).
-2) Lots of testing
-
-GPIO trigger
-1) Add control over the type of interrupt etc.  This will
-necessitate a header that is also visible from arch board
-files. (avoided at the moment to keep the driver set
-contained in staging).
+2016 10/09
 
 ADI Drivers:
 CC the device-drivers-devel@blackfin.uclinux.org mailing list when
 e-mailing the normal IIO list (see below).
 
-Documentation
-1) Lots of cleanup and expansion.
-2) Some device require individual docs.

- * Transfer.
- *
- * There are two possible modes of transfer initiation on the client:
- *
- *     - immediate transfer: this is started when a high level io wants a page
- *       or a collection of pages to be transferred right away. Examples:
- *       read-ahead, synchronous read in the case of non-page aligned write,
- *       page write-out as a part of extent lock cancellation, page write-out
- *       as a part of memory cleansing. Immediate transfer can be both
- *       cl_req_type::CRT_READ and cl_req_type::CRT_WRITE;
- *
- *     - opportunistic transfer (cl_req_type::CRT_WRITE only), that happens
- *       when io wants to transfer a page to the server some time later, when
- *       it can be done efficiently. Example: pages dirtied by the write(2)
- *       path.
- *
- * In any case, transfer takes place in the form of a cl_req, which is a
- * representation for a network RPC.
- *
- * Pages queued for an opportunistic transfer are cached until it is decided
- * that efficient RPC can be composed of them. This decision is made by "a
- * req-formation engine", currently implemented as a part of osc
- * layer. Req-formation depends on many factors: the size of the resulting
- * RPC, whether or not multi-object RPCs are supported by the server,
- * max-rpc-in-flight limitations, size of the dirty cache, etc.
- *
- * For the immediate transfer io submits a cl_page_list, that req-formation
- * engine slices into cl_req's, possibly adding cached pages to some of
- * the resulting req's.
- *
- * Whenever a page from cl_page_list is added to a newly constructed req, its
- * cl_page_operations::cpo_prep() layer methods are called. At that moment,
- * page state is atomically changed from cl_page_state::CPS_OWNED to
- * cl_page_state::CPS_PAGEOUT or cl_page_state::CPS_PAGEIN, cl_page::cp_owner
- * is zeroed, and cl_page::cp_req is set to the
- * req. cl_page_operations::cpo_prep() method at the particular layer might
- * return -EALREADY to indicate that it does not need to submit this page
- * at all. This is possible, for example, if page, submitted for read,
- * became up-to-date in the meantime; and for write, the page don't have
- * dirty bit marked. \see cl_io_submit_rw()
- *
- * Whenever a cached page is added to a newly constructed req, its
- * cl_page_operations::cpo_make_ready() layer methods are called. At that
- * moment, page state is atomically changed from cl_page_state::CPS_CACHED to
- * cl_page_state::CPS_PAGEOUT, and cl_page::cp_req is set to
- * req. cl_page_operations::cpo_make_ready() method at the particular layer
- * might return -EAGAIN to indicate that this page is not eligible for the
- * transfer right now.
- *
- * FUTURE
- *
- * Plan is to divide transfers into "priority bands" (indicated when
- * submitting cl_page_list, and queuing a page for the opportunistic transfer)
- * and allow glueing of cached pages to immediate transfers only within single
- * band. This would make high priority transfers (like lock cancellation or
- * memory pressure induced write-out) really high priority.

+	 *   as long as users adhere to the convention of registering policies
+	 *   in init() and unregistering them in module exit() functions, there
+	 *   should not be a race between these operations.

-The reason why cec.c is still in staging is that I would like
-to have a bit more confidence in the uABI. The kABI is fine,
-no problem there, but I would like to let the public API mature
-a bit.
-
-Once I'm confident that I didn't miss anything then the cec.c source
-can move to drivers/media and the linux/cec.h and linux/cec-funcs.h
-headers can move to uapi/linux and added to uapi/linux/Kbuild to make
-them public.
-
-Hopefully this will happen later in 2016.
-
-Other TODOs:
-
-- There are two possible replies to CEC_MSG_INITIATE_ARC. How to handle that?
-- Add a flag to inhibit passing CEC RC messages to the rc subsystem.
-  Applications should be able to choose this when calling S_LOG_ADDRS.
-- If the reply field of cec_msg is set then when the reply arrives it
-  is only sent to the filehandle that transmitted the original message
-  and not to any followers. Should this behavior change or perhaps
-  controlled through a cec_msg flag?
-- Should CEC_LOG_ADDR_TYPE_SPECIFIC be replaced by TYPE_2ND_TV and TYPE_PROCESSOR?
-  And also TYPE_SWITCH and TYPE_CDC_ONLY in addition to the TYPE_UNREGISTERED?
-  This should give the framework more information about the device type
-  since SPECIFIC and UNREGISTERED give no useful information.
-- Once this is out of staging this should no longer be a separate
-  config option, instead it should be selected by drivers that want it.
-- Revisit the IS_REACHABLE(RC_CORE): perhaps the RC_CORE support should
-  be enabled through a separate config option in drivers/media/Kconfig
-  or rc/Kconfig?

- * Steve's changes to improve transmission fidelity:
- *   - for systems with the rdtsc instruction and the clock counter, a
- *     send_pule that times the pulses directly using the counter.
- *     This means that the LIRC_SERIAL_TRANSMITTER_LATENCY fudge is
- *     not needed. Measurement shows very stable waveform, even where
- *     PCI activity slows the access to the UART, which trips up other
- *     versions.
- *   - For other system, non-integer-microsecond pulse/space lengths,
- *     done using fixed point binary. So, much more accurate carrier
- *     frequency.
- *   - fine tuned transmitter latency, taking advantage of fractional
- *     microseconds in previous change
- *   - Fixed bug in the way transmitter latency was accounted for by
- *     tuning the pulse lengths down - the send_pulse routine ignored
- *     this overhead as it timed the overall pulse length - so the
- *     pulse frequency was right but overall pulse length was too
- *     long. Fixed by accounting for latency on each pulse/space
- *     iteration.

-This driver needs to mature a bit more and another round of
-code cleanups.
-
-Otherwise it looks to be in good shape. And of course the fact
-that the CEC framework is in staging at the moment also prevents
-this driver from being mainlined.
-
-Some notes:
-
-1) Regarding the "autonomous" mode of the Pulse-Eight: currently this
-is disabled, but the idea is that this allows basic functionality
-when the PC is off, and it can wake-up the PC through USB.
-
-To prevent the device to go into autonomous mode the driver would
-have to send MSGCODE_SET_CONTROLLED 1 and then send a ping every
-30 seconds (in practice once every 15 seconds would be good). When
-powering off or going to standby send MSGCODE_SET_CONTROLLED 0 to
-turn the autonomous mode back on.
-
-This needs to be implemented in the driver. Autonomous mode was
-added in firmware v2.
-
-2) Writing to the EEPROM can only be done once every 10 seconds.
-
-3) To use this driver you also need to patch the inputattach utility,
-this patch will be submitted once this driver is moved out of staging.

-TODO:
-	- move firmware loading to request_firmware()
-	- remove direct memory access of structures
-	- any remaining sparse and checkpatch.pl warnings
-
-	- use net_device_ops
-	- use dev->stats rather than adapter->stats
-	- don't cast netdev_priv it is already void
-	- GET RID OF MACROS
-	- work on all architectures
-	   - without CONFIG_X86_64 confusion
-	   - do 64 bit correctly
-	   - don't depend on order of union
-	- get rid of ASSERT(), use BUG() instead but only where necessary
-	  looks like most aren't really useful
-	- no new SIOCDEVPRIVATE ioctl allowed
-	- don't use module_param for configuring interrupt mitigation
-	  use ethtool instead
-	- reorder code to elminate use of forward declarations
-	- don't keep private linked list of drivers.
-	- use PCI_DEVICE()
-	- do ethtool correctly using ethtool_ops
-	- NAPI?
-	- wasted overhead of extra stats
-	- state variables for things that are
-	  easily available and shouldn't be kept in card structure, cardnum, ...
-	  slotnumber, events, ...
-	- volatile == bad design => bad code
-	- locking too fine grained, not designed just throw more locks

+1) Port to aarch64
+
+This driver won't be very useful unless we also have it working on
+Raspberry Pi 3.  This requires, at least:
+
+  - Figure out an alternative to the dmac_map_area() hack.
+
+  - Decide what to use instead of dsb().
+
+  - Do something about (int) cast of bulk->data in
+    vchiq_bulk_transfer().
+
+    bulk->data is a bus address going across to the firmware.  We know
+    our bus addresses are <32bit.
+
+2) Write a DT binding doc and get the corresponding DT node merged to
+   bcm2835.
+
+This will let the driver probe when enabled.
+
+3) Import drivers using VCHI.
+
+VCHI is just a tool to let drivers talk to the firmware.  Here are
+some of the ones we want:
+
+  - vc_mem (https://github.com/raspberrypi/linux/blob/rpi-4.4.y/drivers/char/broadcom/vc_mem.c)
+
+  This driver is what the vcdbg userspace program uses to set up its
+  requests to the firmware, which are transmitted across VCHIQ.  vcdbg
+  is really useful for debugging firmware interactions.
+
+  - bcm2835-camera (https://github.com/raspberrypi/linux/tree/rpi-4.4.y/drivers/media/platform/bcm2835)
+
+  This driver will let us get images from the camera using the MMAL
+  protocol over VCHI.
+
+  - VCSM (https://github.com/raspberrypi/linux/tree/rpi-4.4.y/drivers/char/broadcom/vc_sm)
+
+  This driver is used for talking about regions of VC memory across
+  firmware protocols including VCHI.  We'll want to extend this driver
+  to manage these buffers as dmabufs so that we can zero-copy import
+  camera images into vc4 for rendering/display.
+
+4) Garbage-collect unused code
+
+One of the reasons this driver wasn't upstreamed previously was that
+there's a lot code that got built that's probably unnecessary these
+days.  Once we have the set of VCHI-using drivers we want in tree, we
+should be able to do a sweep of the code to see what's left that's
+unused.

-* This file implements functions that correspond to the prism2/hfa384x
-* 802.11 MAC hardware and firmware host interface.
-*
-* The functions can be considered to represent several levels of
-* abstraction.  The lowest level functions are simply C-callable wrappers
-* around the register accesses.  The next higher level represents C-callable
-* prism2 API functions that match the Intersil documentation as closely
-* as is reasonable.  The next higher layer implements common sequences
-* of invocations of the API layer (e.g. write to bap, followed by cmd).
-*
-* Common sequences:
-* hfa384x_drvr_xxx	Highest level abstractions provided by the
-*			hfa384x code.  They are driver defined wrappers
-*			for common sequences.  These functions generally
-*			use the services of the lower levels.
-*
-* hfa384x_drvr_xxxconfig  An example of the drvr level abstraction. These
-*			functions are wrappers for the RID get/set
-*			sequence. They call copy_[to|from]_bap() and
-*			cmd_access(). These functions operate on the
-*			RIDs and buffers without validation. The caller
-*			is responsible for that.
-*
-* API wrapper functions:
-* hfa384x_cmd_xxx	functions that provide access to the f/w commands.
-*			The function arguments correspond to each command
-*			argument, even command arguments that get packed
-*			into single registers.  These functions _just_
-*			issue the command by setting the cmd/parm regs
-*			& reading the status/resp regs.  Additional
-*			activities required to fully use a command
-*			(read/write from/to bap, get/set int status etc.)
-*			are implemented separately.  Think of these as
-*			C-callable prism2 commands.
-*
-* Lowest Layer Functions:
-* hfa384x_docmd_xxx	These functions implement the sequence required
-*			to issue any prism2 command.  Primarily used by the
-*			hfa384x_cmd_xxx functions.
-*
-* hfa384x_bap_xxx	BAP read/write access functions.
-*			Note: we usually use BAP0 for non-interrupt context
-*			 and BAP1 for interrupt context.
-*
-* hfa384x_dl_xxx	download related functions.
-*
-* Driver State Issues:
-* Note that there are two pairs of functions that manage the
-* 'initialized' and 'running' states of the hw/MAC combo.  The four
-* functions are create(), destroy(), start(), and stop().  create()
-* sets up the data structures required to support the hfa384x_*
-* functions and destroy() cleans them up.  The start() function gets
-* the actual hardware running and enables the interrupts.  The stop()
-* function shuts the hardware down.  The sequence should be:
-* create()
-* start()
-*  .
-*  .  Do interesting things w/ the hardware
-*  .
-* stop()
-* destroy()
-*
-* Note that destroy() can be called without calling stop() first.
