+/*
+ * This driver implements the regmap operations for a generic SPI
+ * master to access the registers of the spi slave chip which has an
+ * Avalone bus in it.
+ *
+ * The "SPI slave to Avalon Master Bridge" (spi-avmm) IP should be integrated
+ * in the spi slave chip. The IP acts as a bridge to convert encoded streams of
+ * bytes from the host to the internal register read/write on Avalon bus. In
+ * order to issue register access requests to the slave chip, the host should
+ * send formatted bytes that conform to the transfer protocol.
+ * The transfer protocol contains 3 layers: transaction layer, packet layer
+ * and physical layer.
+ *
+ * Reference Documents could be found at:
+ * https://www.intel.com/content/www/us/en/programmable/documentation/sfo1400787952932.html
+ *
+ * Chapter "SPI Slave/JTAG to Avalon Master Bridge Cores" is a general
+ * introduction to the protocol.
+ *
+ * Chapter "Avalon Packets to Transactions Converter Core" describes
+ * the transaction layer.
+ *
+ * Chapter "Avalon-ST Bytes to Packets and Packets to Bytes Converter Cores"
+ * describes the packet layer.
+ *
+ * Chapter "Avalon-ST Serial Peripheral Interface Core" describes the
+ * physical layer.
+ *
+ *
+ * When host issues a regmap read/write, the driver will transform the request
+ * to byte stream layer by layer. It formats the register addr, value and
+ * length to the transaction layer request, then converts the request to packet
+ * layer bytes stream and then to physical layer bytes stream. Finally the
+ * driver sends the formatted byte stream over SPI bus to the slave chip.
+ *
+ * The spi-avmm IP on the slave chip decodes the byte stream and initiates
+ * register read/write on its internal Avalon bus, and then encodes the
+ * response to byte stream and sends back to host.
+ *
+ * The driver receives the byte stream, reverses the 3 layers transformation,
+ * and finally gets the response value (read out data for register read,
+ * successful written size for register write).

+ * @max_waves_per_cu: Output parameter updated with maximum number of waves

+ *
+ * @note: It's possible that the device has too many queues (oversubscription)
+ * in which case a VMID could be remapped to a different PASID. This could lead
+ * to an iaccurate wave count. Following is a high-level sequence:
+ *    Time T1: vmid = getVmid(); vmid is associated with Pasid P1
+ *    Time T2: passId = getPasId(vmid); vmid is associated with Pasid P2
+ * In the sequence above wave count obtained from time T1 will be incorrectly
+ * lost or added to total wave count.
+ *
+ * The registers that provide the waves in flight are:
+ *
+ *  SPI_CSQ_WF_ACTIVE_STATUS - bit-map of queues per pipe. The bit is ON if a
+ *  queue is slotted, OFF if there is no queue. A process could have ZERO or
+ *  more queues slotted and submitting waves to be run on compute units. Even
+ *  when there is a queue it is possible there could be zero wave fronts, this
+ *  can happen when queue is waiting on top-of-pipe events - e.g. waitRegMem
+ *  command
+ *
+ *  For each bit that is ON from above:
+ *
+ *    Read (SPI_CSQ_WF_ACTIVE_COUNT_0 + queue_idx) register. It provides the
+ *    number of waves that are in flight for the queue at specified index. The
+ *    index ranges from 0 to 7.
+ *
+ *    If non-zero waves are in flight, read CP_HQD_VMID register to obtain VMID
+ *    of the wave(s).
+ *
+ *    Determine if VMID from above step maps to pasid provided as parameter. If
+ *    it matches agrregate the wave count. That the VMID will not match pasid is
+ *    a normal condition i.e. a device is expected to support multiple queues
+ *    from multiple proceses.
+ *
+ *  Reading registers referenced above involves programming GRBM appropriately

+	 *  All CU's of a device are available for the process. This may not be true
+	 *  under certain conditions - e.g. CU masking.

  *
- * The PL111 is a simple LCD controller that can support TFT and STN
- * displays.  This driver exposes a standard KMS interface for them.
- *
- * This driver uses the same Device Tree binding as the fbdev CLCD
- * driver.  While the fbdev driver supports panels that may be
- * connected to the CLCD internally to the CLCD driver, in DRM the
- * panels get split out to drivers/gpu/drm/panels/.  This means that,

+-*- org -*-
+
+* On/off LEDs should have max_brightness of 1
+* Get rid of enum led_brightness
+
+It is really an integer, as maximum is configurable. Get rid of it, or
+make it into typedef or something.
+
+* Review atomicity requirements in LED subsystem
+
+Calls that may and that may not block are mixed in same structure, and
+semantics is sometimes non-intuitive. (For example blink callback may
+not sleep.) Review the requirements for any bugs and document them
+clearly.
+
+* LED names are still a mess
+
+No two LEDs have same name, so the names are probably unusable for the
+userland. Nudge authors into creating common LED names for common
+functionality.
+
+? Perhaps check for known LED names during boot, and warn if there are
+LEDs not on the list?
+
+* Split drivers into subdirectories
+
+The number of drivers is getting big, and driver for on/off LED on a
+i/o port is really quite different from camera flash LED, which is
+really different from driver for RGB color LED that can run its own
+microcode. Split the drivers somehow.
+
+* Figure out what to do with RGB leds
+
+Multicolor is a bit too abstract. Yes, we can have
+Green-Magenta-Ultraviolet LED, but so far all the LEDs we support are
+RGB, and not even RGB-White or RGB-Yellow variants emerged.
+
+Multicolor is not a good fit for RGB LED. It does not really know
+about LED color.  In particular, there's no way to make LED "white".
+
+Userspace is interested in knowing "this LED can produce arbitrary
+color", which not all multicolor LEDs can.
+
+	Proposal: let's add "rgb" to led_colors in drivers/leds/led-core.c,
+	add corresponding device tree defines, and use that, instead of
+	multicolor for RGB LEDs.
+
+	We really need to do that now; "white" stuff can wait.
+
+RGB LEDs are quite common, and it would be good to be able to turn LED
+white and to turn it into any arbitrary color. It is essential that
+userspace is able to set arbitrary colors, and it might be good to
+have that ability from kernel, too... to allow full-color triggers.
+
+* Command line utility to manipulate the LEDs?
+
+/sys interface is not really suitable to use by hand, should we have
+an utility to perform LED control?
+
+In particular, LED names are still a mess (see above) and utility
+could help there by presenting both old and new names while we clean
+them up.
+
+In future, I'd like utility to accept both old and new names while we
+clean them up.
+
+It would be also nice to have useful listing mode -- name, type,
+current brightness/trigger...
+
+In future, it would be good to be able to set rgb led to particular
+color.
+
+And probably user-friendly interface to access LEDs for particular
+ethernet interface would be nice.

+ * @ctx: Encoder-specific state.
+ * @stream_id: Examples: Audio streams (0xc0-0xdf), Video streams
+ * (0xe0-0xef).
+ * @es_id: The TS PID to use for the elementary stream in this encoder.
+ * @encode: Prepare enough AUs for the given amount of time.

-/*
- * The COSM driver uses SCIF to communicate between the management node and the
- * MIC cards. SCIF is used to (a) Send a shutdown command to the card (b)
- * receive a shutdown status back from the card upon completion of shutdown and
- * (c) receive periodic heartbeat messages from the card used to deduce if the
- * card has crashed.
- *
- * A COSM server consisting of a SCIF listening endpoint waits for incoming
- * connections from the card. Upon acceptance of the connection, a separate
- * work-item is scheduled to handle SCIF message processing for that card. The
- * life-time of this work-item is therefore the time from which the connection
- * from a card is accepted to the time at which the connection is closed. A new
- * work-item starts each time the card boots and is alive till the card (a)
- * shuts down (b) is reset (c) crashes (d) cosm_client driver on the card is
- * unloaded.
- *
- * From the point of view of COSM interactions with SCIF during card
- * shutdown, reset and crash are as follows:
- *
- * Card shutdown
- * -------------
- * 1. COSM client on the card invokes orderly_poweroff() in response to SHUTDOWN
- *    message from the host.
- * 2. Card driver shutdown callback invokes scif_unregister_device(..) resulting
- *    in scif_remove(..) getting called on the card
- * 3. scif_remove -> scif_stop -> scif_handle_remove_node ->
- *    scif_peer_unregister_device -> device_unregister for the host peer device
- * 4. During device_unregister remove(..) method of cosm_client is invoked which
- *    closes the COSM SCIF endpoint on the card. This results in a SCIF_DISCNCT
- *    message being sent to host SCIF. SCIF_DISCNCT message processing on the
- *    host SCIF sets the host COSM SCIF endpoint state to DISCONNECTED and wakes
- *    up the host COSM thread blocked in scif_poll(..) resulting in
- *    scif_poll(..)  returning EPOLLHUP.
- * 5. On the card, scif_peer_release_dev is next called which results in an
- *    SCIF_EXIT message being sent to the host and after receiving the
- *    SCIF_EXIT_ACK from the host the peer device teardown on the card is
- *    complete.
- * 6. As part of the SCIF_EXIT message processing on the host, host sends a
- *    SCIF_REMOVE_NODE to itself corresponding to the card being removed. This
- *    starts a similar SCIF peer device teardown sequence on the host
- *    corresponding to the card being shut down.
- *
- * Card reset
- * ----------
- * The case of interest here is when the card has not been previously shut down
- * since most of the steps below are skipped in that case:
-
- * 1. cosm_stop(..) invokes hw_ops->stop(..) method of the base PCIe driver
- *    which unregisters the SCIF HW device resulting in scif_remove(..) being
- *    called on the host.
- * 2. scif_remove(..) calls scif_disconnect_node(..) which results in a
- *    SCIF_EXIT message being sent to the card.
- * 3. The card executes scif_stop() as part of SCIF_EXIT message
- *    processing. This results in the COSM endpoint on the card being closed and
- *    the SCIF host peer device on the card getting unregistered similar to
- *    steps 3, 4 and 5 for the card shutdown case above. scif_poll(..) on the
- *    host returns EPOLLHUP as a result.
- * 4. On the host, card peer device unregister and SCIF HW remove(..) also
- *    subsequently complete.
- *
- * Card crash
- * ----------
- * If a reset is issued after the card has crashed, there is no SCIF_DISCNT
- * message from the card which would result in scif_poll(..) returning
- * EPOLLHUP. In this case when the host SCIF driver sends a SCIF_REMOVE_NODE
- * message to itself resulting in the card SCIF peer device being unregistered,
- * this results in a scif_peer_release_dev -> scif_cleanup_scifdev->
- * scif_invalidate_ep call sequence which sets the endpoint state to
- * DISCONNECTED and results in scif_poll(..) returning EPOLLHUP.

- * SCIF connection flow:
- *
- * 1) A SCIF listening endpoint can call scif_accept(..) to wait for SCIF
- *	connections via a SCIF_CNCT_REQ message
- * 2) A SCIF endpoint can initiate a SCIF connection by calling
- *	scif_connect(..) which calls scif_setup_qp_connect(..) which
- *	allocates the local qp for the endpoint ring buffer and then sends
- *	a SCIF_CNCT_REQ to the remote node and waits for a SCIF_CNCT_GNT or
- *	a SCIF_CNCT_REJ message
- * 3) The peer node handles a SCIF_CNCT_REQ via scif_cnctreq_resp(..) which
- *	wakes up any threads blocked in step 1 or sends a SCIF_CNCT_REJ
- *	message otherwise
- * 4) A thread blocked waiting for incoming connections allocates its local
- *	endpoint QP and ring buffer following which it sends a SCIF_CNCT_GNT
- *	and waits for a SCIF_CNCT_GNT(N)ACK. If the allocation fails then
- *	the node sends a SCIF_CNCT_REJ message
- * 5) Upon receipt of a SCIF_CNCT_GNT or a SCIF_CNCT_REJ message the
- *	connecting endpoint is woken up as part of handling
- *	scif_cnctgnt_resp(..) following which it maps the remote endpoints'
- *	QP, updates its outbound QP and sends a SCIF_CNCT_GNTACK message on
- *	success or a SCIF_CNCT_GNTNACK message on failure and completes
- *	the scif_connect(..) API
- * 6) Upon receipt of a SCIF_CNCT_GNT(N)ACK the accepting endpoint blocked
- *	in step 4 is woken up and completes the scif_accept(..) API
- * 7) The SCIF connection is now established between the two SCIF endpoints.

- ************************************************************************
- * SCIF node Queue Pair (QP) setup flow:
- *
- * 1) SCIF driver gets probed with a scif_hw_dev via the scif_hw_bus
- * 2) scif_setup_qp(..) allocates the local qp and calls
- *	scif_setup_qp_connect(..) which allocates and maps the local
- *	buffer for the inbound QP
- * 3) The local node updates the device page with the DMA address of the QP
- * 4) A delayed work is scheduled (qp_dwork) which periodically reads if
- *	the peer node has updated its QP DMA address
- * 5) Once a valid non zero address is found in the QP DMA address field
- *	in the device page, the local node maps the remote node's QP,
- *	updates its outbound QP and sends a SCIF_INIT message to the peer
- * 6) The SCIF_INIT message is received by the peer node QP interrupt bottom
- *	half handler by calling scif_init(..)
- * 7) scif_init(..) registers a new SCIF peer node by calling
- *	scif_peer_register_device(..) which signifies the addition of a new
- *	SCIF node
- * 8) On the mgmt node, P2P network setup/teardown is initiated if all the
- *	remote nodes are online via scif_p2p_setup(..)
- * 9) For P2P setup, the host maps the remote nodes' aperture and memory
- *	bars and sends a SCIF_NODE_ADD message to both nodes
- * 10) As part of scif_nodeadd, both nodes set up their local inbound
- *	QPs and send a SCIF_NODE_ADD_ACK to the mgmt node
- * 11) As part of scif_node_add_ack(..) the mgmt node forwards the
- *	SCIF_NODE_ADD_ACK to the remote nodes
- * 12) As part of scif_node_add_ack(..) the remote nodes update their
- *	outbound QPs, make sure they can access memory on the remote node
- *	and then add a new SCIF peer node by calling
- *	scif_peer_register_device(..) which signifies the addition of a new
- *	SCIF node.
- * 13) The SCIF network is now established across all nodes.
- *
- ************************************************************************
- * SCIF node QP teardown flow (initiated by non mgmt node):
- *
- * 1) SCIF driver gets a remove callback with a scif_hw_dev via the scif_hw_bus
- * 2) The device page QP DMA address field is updated with 0x0
- * 3) A non mgmt node now cleans up all local data structures and sends a
- *	SCIF_EXIT message to the peer and waits for a SCIF_EXIT_ACK
- * 4) As part of scif_exit(..) handling scif_disconnect_node(..) is called
- * 5) scif_disconnect_node(..) sends a SCIF_NODE_REMOVE message to all the
- *	peers and waits for a SCIF_NODE_REMOVE_ACK
- * 6) As part of scif_node_remove(..) a remote node unregisters the peer
- *	node from the SCIF network and sends a SCIF_NODE_REMOVE_ACK
- * 7) When the mgmt node has received all the SCIF_NODE_REMOVE_ACKs
- *	it sends itself a node remove message whose handling cleans up local
- *	data structures and unregisters the peer node from the SCIF network
- * 8) The mgmt node sends a SCIF_EXIT_ACK
- * 9) Upon receipt of the SCIF_EXIT_ACK the node initiating the teardown
- *	completes the SCIF remove routine
- * 10) The SCIF network is now torn down for the node initiating the
- *	teardown sequence
- *

- * 8) A non mgmt node upon receipt of a SCIF_EXIT message calls scif_stop(..)
- *	which would clean up local data structures for all SCIF nodes and
- *	then send a SCIF_EXIT_ACK back to the mgmt node
- * 9) Upon receipt of the SCIF_EXIT_ACK the the mgmt node sends itself a node
- *	remove message whose handling cleans up local data structures and
- *	destroys any P2P mappings.
- * 10) The SCIF hardware device for which a remove callback was received is now
- *	disconnected from the SCIF network.

- *
- * This work queue routine is triggered when a loopback message is received.

- * We need special handling for receiving Node Qp messages on a loopback SCIF
- * device via two workqueues for receiving messages.
- *
- * The reason we need the extra workqueue which is not required with *normal*
- * non-loopback SCIF devices is the potential classic deadlock described below:
- *
- * Thread A tries to send a message on a loopback SCIF device and blocks since
- * there is no space in the RB while it has the send_lock held or another
- * lock called lock X for example.
- *
- * Thread B: The Loopback Node QP message receive workqueue receives the message
- * and tries to send a message (eg an ACK) to the loopback SCIF device. It tries
- * to grab the send lock again or lock X and deadlocks with Thread A. The RB
- * cannot be drained any further due to this classic deadlock.
- *
- * In order to avoid deadlocks as mentioned above we have an extra level of

+	 *    a) The clock divisor for SDR12, SDR25, and SDR50 is too small.
+	 *       This results in clock frequencies that are 2x higher than
+	 *       acceptable. i.e., SDR12 = 25 MHz, SDR25 = 50 MHz, SDR50 =
+	 *       100 MHz.x
+	 *    b) The HS200 and HS400 driver strengths don't match.
+	 *       By default, the SDR104 preset register has a driver strength of
+	 *       A, but the (internal) HS400 preset register has a driver
+	 *       strength of B. As part of initializing HS400, HS200 tuning
+	 *       needs to be performed. Having different driver strengths
+	 *       between tuning and operation is wrong. It results in different
+	 *       rise/fall times that lead to incorrect sampling.
+	 * 2) Firmware with properly initialized presets.
+	 *    These presets have proper clock divisors. i.e., SDR12 => 12MHz,
+	 *    SDR25 => 25 MHz, SDR50 => 50 MHz. Additionally the HS200 and
+	 *    HS400 preset driver strengths match.
+	 *
+	 *    Enabling presets for HS400 doesn't work for the following reasons:
+	 *    1) sdhci_set_ios has a hard coded list of timings that are used
+	 *       to determine if presets should be enabled.
+	 *    2) sdhci_get_preset_value is using a non-standard register to
+	 *       read out HS400 presets. The AMD controller doesn't support this
+	 *       non-standard register. In fact, it doesn't expose the HS400
+	 *       preset register anywhere in the SDHCI memory map. This results
+	 *       in reading a garbage value and using the wrong presets.
+	 *
+	 *       Since HS400 and HS200 presets must be identical, we could
+	 *       instead use the the SDR104 preset register.
+	 *
+	 *    If the above issues are resolved we could remove this quirk for
+	 *    firmware that that has valid presets (i.e., SDR12 <= 12 MHz).

+ * Generic Error-Correcting Code (ECC) engine
+ *
+ * Copyright (C) 2019 Macronix
+ * Author:
+ *     Miquèl RAYNAL <miquel.raynal@bootlin.com>
+ *
+ *
+ * This file describes the abstraction of any NAND ECC engine. It has been
+ * designed to fit most cases, including parallel NANDs and SPI-NANDs.
+ *
+ * There are three main situations where instantiating this ECC engine makes
+ * sense:
+ *   - external: The ECC engine is outside the NAND pipeline, typically this
+ *               is a software ECC engine, or an hardware engine that is
+ *               outside the NAND controller pipeline.
+ *   - pipelined: The ECC engine is inside the NAND pipeline, ie. on the
+ *                controller's side. This is the case of most of the raw NAND
+ *                controllers. In the pipeline case, the ECC bytes are
+ *                generated/data corrected on the fly when a page is
+ *                written/read.
+ *   - ondie: The ECC engine is inside the NAND pipeline, on the chip's side.
+ *            Some NAND chips can correct themselves the data.
+ *
+ * Besides the initial setup and final cleanups, the interfaces are rather
+ * simple:
+ *   - prepare: Prepare an I/O request. Enable/disable the ECC engine based on
+ *              the I/O request type. In case of software correction or external
+ *              engine, this step may involve to derive the ECC bytes and place
+ *              them in the OOB area before a write.
+ *   - finish: Finish an I/O request. Correct the data in case of a read
+ *             request and report the number of corrected bits/uncorrectable
+ *             errors. Most likely empty for write operations, unless you have
+ *             hardware specific stuff to do, like shutting down the engine to
+ *             save power.
+ *
+ * The I/O request should be enclosed in a prepare()/finish() pair of calls
+ * and will behave differently depending on the requested I/O type:
+ *   - raw: Correction disabled
+ *   - ecc: Correction enabled
+ *
+ * The request direction is impacting the logic as well:
+ *   - read: Load data from the NAND chip
+ *   - write: Store data in the NAND chip
+ *
+ * Mixing all this combinations together gives the following behavior.
+ * Those are just examples, drivers are free to add custom steps in their
+ * prepare/finish hook.
+ *
+ * [external ECC engine]
+ *   - external + prepare + raw + read: do nothing
+ *   - external + finish  + raw + read: do nothing

+ *                                      and report any bitflip/error
+ *   - external + prepare + ecc + write: calculate ECC bytes and store them at
+ *                                       the right place in the OOB buffer based

+ * - PTP_PULSE_OUT (PTP_EVENT_REQ MPP)
+ *   It looks like the hardware can't generate a pulse at nsec=0. (The
+ *   output doesn't trigger if the nsec field is zero.)
+ *   Note: when configured as an output via the register at 0xfX441120,
+ *   the input is still very much alive, and will trigger the current TCF
+ *   function.
+ * - PTP_CLK_OUT (PTP_TRIG_GEN MPP)
+ *   This generates a "PPS" signal determined by the CCC registers. It

+	 * registers, which is how we get to interact with it. And since the
+	 * VCAP_ENTRY_DAT cache registers access only the subwords and not the

+ *
+ * There is no public datasheet available for this PWM core. But it is easy
+ * enough to be briefly explained. It consists of one 8-bit counter. The PWM
+ * supports four distinct frequencies by selecting when to reset the counter.
+ * With the prescaler setting you can select which bit of the counter is used
+ * to reset it. This implies that the higher the frequency the less remaining
+ * bits are available for the actual counter.
+ *
+ * Let cnt[7:0] be the counter, clocked at 32kHz:
+ * +-----------+--------+--------------+-----------+---------------+
+ * | prescaler |  reset | counter bits | frequency | period length |
+ * +-----------+--------+--------------+-----------+---------------+
+ * |         0 | cnt[7] |     cnt[6:0] |    250 Hz |    4000000 ns |
+ * |         1 | cnt[6] |     cnt[5:0] |    500 Hz |    2000000 ns |
+ * |         2 | cnt[5] |     cnt[4:0] |     1 kHz |    1000000 ns |
+ * |         3 | cnt[4] |     cnt[3:0] |     2 kHz |     500000 ns |
+ * +-----------+--------+--------------+-----------+---------------+
+ *
+ * Limitations:
+ * - The hardware cannot generate a 100% duty cycle if the prescaler is 0.
+ * - The hardware cannot atomically set the prescaler and the counter value,
+ *   which might lead to glitches and inconsistent states if a write fails.
+ * - The counter is not reset if you switch the prescaler which leads
+ *   to glitches, too.
+ * - The duty cycle will switch immediately and not after a complete cycle.
+ * - Depending on the actual implementation, disabling the PWM might have
+ *   side effects. For example, if the output pin is shared with a GPIO pin
+ *   it will automatically switch back to GPIO mode.

+ * settings. However, some individual settings cannot be set in LockStep mode.
+ * This is overcome by switching to Split-mode initially and then programming

+/* The read-ahead cache present in the Brahma-B53 CPU is a special piece of
+ * hardware after the integrated L2 cache of the B53 CPU complex whose purpose
+ * is to prefetch instruction and/or data with a line size of either 64 bytes
+ * or 256 bytes. The rationale is that the data-bus of the CPU interface is
+ * optimized for 256-byte transactions, and enabling the read-ahead cache
+ * provides a significant performance boost (typically twice the performance
+ * for a memcpy benchmark application).
+ *
+ * The read-ahead cache is transparent for Virtual Address cache maintenance
+ * operations: IC IVAU, DC IVAC, DC CVAC, DC CVAU and DC CIVAC.  So no special
+ * handling is needed for the DMA API above and beyond what is included in the
+ * arm64 implementation.
+ *
+ * In addition, since the Point of Unification is typically between L1 and L2
+ * for the Brahma-B53 processor no special read-ahead cache handling is needed
+ * for the IC IALLU and IC IALLUIS cache maintenance operations.
+ *
+ * However, it is not possible to specify the cache level (L3) for the cache
+ * maintenance instructions operating by set/way to operate on the read-ahead
+ * cache.  The read-ahead cache will maintain coherency when inner cache lines
+ * are cleaned by set/way, but if it is necessary to invalidate inner cache
+ * lines by set/way to maintain coherency with system masters operating on
+ * shared memory that does not have hardware support for coherency, then it
+ * will also be necessary to explicitly invalidate the read-ahead cache.

+ * In order to solve the problem we have to feed the DMA engine with SG list
+ * entries one-by-one. It shall keep the DW APB SSI Tx and Rx FIFOs
+ * synchronized and prevent the Rx FIFO overflow. Since in general the tx_sg
+ * and rx_sg lists may have different number of entries of different lengths
+ * (though total length should match) let's virtually split the SG-lists to the

-Kernel driver max517
-====================
-
-Supported chips:
-  * Maxim MAX517, MAX518, MAX519
-    Prefix: 'max517'
-    Datasheet: Publicly available at the Maxim website
-               http://www.maxim-ic.com/

-Description
------------
-
-The Maxim MAX517/518/519 is an 8-bit DAC on the I2C bus. The following table
-shows the different feature sets of the variants MAX517, MAX518 and MAX519:
-
-Feature                              MAX517 MAX518 MAX519
---------------------------------------------------------------------------
-One output channel                   X
-Two output channels                         X      X
-Simultaneous output updates                 X      X
-Supply voltage as reference                 X
-Separate reference input             X
-Reference input for each DAC                       X
-
-Via the iio sysfs interface, there are three attributes available: out1_raw,
-out2_raw and out12_raw. With out1_raw and out2_raw, the current output values
-(0..255) of the DACs can be written to the device. out12_raw can be used to set
-both output channel values simultaneously.
-
-With MAX517, only out1_raw is available.
-
-Via out1_scale (and where appropriate, out2_scale), the current scaling factor
-in mV can be read.
-
-When the operating system goes to a power down state, the Power Down function
-of the chip is activated, reducing the supply current to 4uA.
-
-On power-up, the device is in 0V-output state.

-IIO Device drivers
-
-This is not intended to provide a comprehensive guide to writing an
-IIO device driver.  For further information see the drivers within the
-subsystem.
-
-The crucial structure for device drivers in iio is iio_dev.
-
-First allocate one using:
-
-struct iio_dev *indio_dev = iio_device_alloc(parent, sizeof(struct chip_state));
-where chip_state is a structure of local state data for this instance of
-the chip.
-
-That data can be accessed using iio_priv(struct iio_dev *).
-
-Then fill in the following:
-
-- indio_dev->name
-	Name of the device being driven - made available as the name
-	attribute in sysfs.
-
-- indio_dev->info
-	pointer to a structure with elements that tend to be fixed for
-	large sets of different parts supported by a given driver.
-	This contains:
-	* info->event_attrs:
-		Attributes used to enable / disable hardware events.
-	* info->attrs:
-		General device attributes. Typically used for the weird
-		and the wonderful bits not covered by the channel specification.
-	* info->read_raw:
-		Raw data reading function. Used for both raw channel access
-		and for associate parameters such as offsets and scales.
-	* info->write_raw:
-		Raw value writing function. Used for writable device values such
-		as DAC values and calibbias.
-	* info->read_event_config:
-		Typically only set if there are some interrupt lines.  This
-		is used to read if an on sensor event detector is enabled.
-	* info->write_event_config:
-		Enable / disable an on sensor event detector.
-	* info->read_event_value:
-		Read value associated with on sensor event detectors. Note that
-		the meaning of the returned value is dependent on the event
-		type.
-	* info->write_event_value:
-		Write the value associated with on sensor event detectors. E.g.
-		a threshold above which an interrupt occurs.  Note that the
-		meaning of the value to be set is event type dependent.
-
-- indio_dev->modes:
-	Specify whether direct access and / or ring buffer access is supported.
-- indio_dev->buffer:
-	An optional associated buffer.
-- indio_dev->pollfunc:
-	Poll function related elements. This controls what occurs when a trigger
-	to which this device is attached sends an event.
-- indio_dev->channels:
-	Specification of device channels. Most attributes etc. are built
-	from this spec.
-- indio_dev->num_channels:
-	How many channels are there?
-
-Once these are set up, a call to iio_device_register(indio_dev)
-will register the device with the iio core.
-
-Worth noting here is that, if a ring buffer is to be used, it can be
-allocated prior to registering the device with the iio-core, but must
-be registered afterwards (otherwise the whole parentage of devices
-gets confused)
-
-On remove, iio_device_unregister(indio_dev) will remove the device from
-the core, and iio_device_free(indio_dev) will clean up.

-Overview of IIO
-
-The Industrial I/O subsystem is intended to provide support for devices
-that in some sense are analog to digital converters (ADCs). As many
-actual devices combine some ADCs with digital to analog converters
-(DACs) that functionality is also supported.
-
-The aim is to fill the gap between the somewhat similar hwmon and
-input subsystems.  Hwmon is very much directed at low sample rate
-sensors used in applications such as fan speed control and temperature
-measurement.  Input is, as its name suggests focused on input
-devices. In some cases there is considerable overlap between these and
-IIO.
-
-A typical device falling into this category would be connected via SPI
-or I2C.
-
-Functionality of IIO
-
-* Basic device registration and handling. This is very similar to
-hwmon with simple polled access to device channels via sysfs.
-
-* Event chrdevs.  These are similar to input in that they provide a
-route to user space for hardware triggered events. Such events include
-threshold detectors, free-fall detectors and more complex action
-detection.  The events themselves are currently very simple with
-merely an event code and a timestamp.  Any data associated with the
-event must be accessed via polling.
-
-Note: A given device may have one or more event channel.  These events are
-turned on or off (if possible) via sysfs interfaces.
-
-* Hardware buffer support.  Some recent sensors have included
-fifo / ring buffers on the sensor chip.  These greatly reduce the load
-on the host CPU by buffering relatively large numbers of data samples
-based on an internal sampling clock. Examples include VTI SCA3000
-series and Analog Devices ADXL345 accelerometers.  Each buffer supports
-polling to establish when data is available.
-
-* Trigger and software buffer support. In many data analysis
-applications it it useful to be able to capture data based on some
-external signal (trigger).  These triggers might be a data ready
-signal, a gpio line connected to some external system or an on
-processor periodic interrupt.  A single trigger may initialize data
-capture or reading from a number of sensors.  These triggers are
-used in IIO to fill software buffers acting in a very similar
-fashion to the hardware buffers described above.
-
-Other documentation:
-
-device.txt - elements of a typical device driver.
-
-trigger.txt - elements of a typical trigger driver.
-
-ring.txt - additional elements required for buffer support.
-
-sysfs-bus-iio - abi documentation file.

-Buffer support within IIO
-
-This document is intended as a general overview of the functionality
-a buffer may supply and how it is specified within IIO.  For more
-specific information on a given buffer implementation, see the
-comments in the source code.  Note that some drivers allow buffer
-implementation to be selected at compile time via Kconfig options.
-
-A given buffer implementation typically embeds a struct
-iio_ring_buffer and it is a pointer to this that is provided to the
-IIO core. Access to the embedding structure is typically done via
-container_of functions.
-
-struct iio_ring_buffer contains a struct iio_ring_setup_ops *setup_ops
-which in turn contains the 4 function pointers
-(preenable, postenable, predisable and postdisable).
-These are used to perform device specific steps on either side
-of the core changing its current mode to indicate that the buffer
-is enabled or disabled (along with enabling triggering etc. as appropriate).
-
-Also in struct iio_ring_buffer is a struct iio_ring_access_funcs.
-The function pointers within here are used to allow the core to handle
-as much buffer functionality as possible. Note almost all of these
-are optional.
-
-store_to
-  If possible, push data to the buffer.
-
-read_last
-  If possible, get the most recent scan from the buffer (without removal).
-  This provides polling like functionality whilst the ring buffering is in
-  use without a separate read from the device.
-
-rip_first_n
-  The primary buffer reading function. Note that it may well not return
-  as much data as requested.
-
-request_update
-  If parameters have changed that require reinitialization or configuration of
-  the buffer this will trigger it.
-
-set_bytes_per_datum
-  Set the number of bytes for a complete scan. (All samples + timestamp)
-
-set_length
-  Set the number of complete scans that may be held by the buffer.

-  driver to do TPG Vs Sensor media links based on CONFIG_VIDEO_TEGRA_TPG.
-* Add real camera sensor capture support.
-* Add Tegra CSI MIPI pads calibration.
-* Add MIPI clock Settle time computation based on the data rate.
 * Add support for Ganged mode.
 * Add RAW10 packed video format support to Tegra210 video formats.

-- fix the disconnect and free-on-last-user handling (i.e., add

- *
- * This module is part of usbvision driver project.
- *
- * Let's call the version 0.... until compression decoding is completely
- * implemented.
- *
- * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
- * It was based on USB CPiA driver written by Peter Pregler,
- * Scott J. Bertin and Johannes Erdfelt
- * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
- * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
- * Updates to driver completed by Dwaine P. Garden
- *
- * TODO:
- *     - use submit_urb for all setup packets
- *     - Fix memory settings for nt1004. It is 4 times as big as the
- *       nt1003 memory.
- *     - Add audio on endpoint 3 for nt1004 chip.
- *         Seems impossible, needs a codec interface.  Which one?
- *     - Clean up the driver.
- *     - optimization for performance.
- *     - Add Videotext capability (VBI).  Working on it.....
- *     - Check audio for other devices

+- MJPEG capture (compression)

+- MJPEG play (decompression)

+	Note: only recent ffmpeg has the ability of sending non-raw video via v4l2
+
+	The original way of sending video was via mplayer vo_zr/vo_zr2, but it does not compile
+	anymore and is a dead end (usage of some old private ffmpeg structures).
+
+TODO
+- fix the v4l compliance "TRY_FMT cannot handle an invalid pixelformat"
+- Filter JPEG data to made output work

+/* Should ease the (re-)usage of drivers supporting cards with (different)
+   video codecs. The codecs register to this module their functionality,
+   and the processors (masters) can attach to them if they fit.
+
+   The codecs are typically have a "strong" binding to their master - so I
+   don't think it makes sense to have a full blown interfacing as with e.g.
+   i2c. If you have an other opinion, let's discuss & implement it :-)))
+
+   Usage:
+
+   The slave has just to setup the videocodec structure and use two functions:
+   videocodec_register(codecdata);
+   videocodec_unregister(codecdata);
+   The best is just calling them at module (de-)initialisation.
+
+   The master sets up the structure videocodec_master and calls:
+   codecdata=videocodec_attach(master_codecdata);
+   videocodec_detach(codecdata);
+
+   The slave is called during attach/detach via functions setup previously
+   during register. At that time, the master_data pointer is set up
+   and the slave can access any io registers of the master device (in the case
+   the slave is bound to it). Otherwise it doesn't need this functions and
+   therfor they may not be initialized.
+
+   The other functions are just for convenience, as they are for sure used by
+   most/all of the codecs. The last ones may be omitted, too.
+
+   See the structure declaration below for more information and which data has
+   to be set up for the master and the slave.
+
+   ----------------------------------------------------------------------------
+   The master should have "knowledge" of the slave and vice versa.  So the data
+   structures sent to/from slave via set_data/get_data set_image/get_image are
+   device dependent and vary between MJPEG/MPEG/WAVELET/... devices. (!!!!)

+   ==== master setup ====
+   name -> name of the device structure for reference and debugging
+   master_data ->  data ref. for the master (e.g. the zr36055,57,67)
+   readreg -> ref. to read-fn from register (setup by master, used by slave)
+   writereg -> ref. to write-fn to register (setup by master, used by slave)
+	       this two functions do the lowlevel I/O job
+
+   ==== slave functionality setup ====
+   slave_data -> data ref. for the slave (e.g. the zr36050,60)
+   check -> fn-ref. checks availability of an device, returns -EIO on failure or
+	    the type on success
+	    this makes espcecially sense if a driver module supports more than
+	    one codec which may be quite similar to access, nevertheless it
+	    is good for a first functionality check
+
+   -- main functions you always need for compression/decompression --
+
+   set_mode -> this fn-ref. resets the entire codec, and sets up the mode
+	       with the last defined norm/size (or device default if not
+	       available) - it returns 0 if the mode is possible
+   set_size -> this fn-ref. sets the norm and image size for
+	       compression/decompression (returns 0 on success)
+	       the norm param is defined in videodev2.h (V4L2_STD_*)
+
+   additional setup may be available, too - but the codec should work with
+   some default values even without this
+
+   set_data -> sets device-specific data (tables, quality etc.)
+   get_data -> query device-specific data (tables, quality etc.)
+
+   if the device delivers interrupts, they may be setup/handled here
+   setup_interrupt -> codec irq setup (not needed for 36050/60)
+   handle_interrupt -> codec irq handling (not needed for 36050/60)
+
+   if the device delivers pictures, they may be handled here
+   put_image -> puts image data to the codec (not needed for 36050/60)
+   get_image -> gets image data from the codec (not needed for 36050/60)
+		the calls include frame numbers and flags (even/odd/...)
+		if needed and a flag which allows blocking until its ready

+
+description:
+  The WFxxx chip series can be connected via SPI or via SDIO.
+
+  For SDIO':'
+
+    The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor
+    ID and Product ID. However, driver will only provide limited features in
+    this case. Thus declaring WFxxx chip in device tree is recommended (and may
+    become mandatory in the future).
+
+    In addition, it is recommended to declare a mmc-pwrseq on SDIO host above
+    WFx. Without it, you may encounter issues with warm boot. The mmc-pwrseq
+    should be compatible with mmc-pwrseq-simple. Please consult
+    Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.yaml for more
+    information.
+
+  For SPI':'
+
+    In add of the properties below, please consult
+    Documentation/devicetree/bindings/spi/spi-controller.yaml for optional SPI
+    related properties.
+
+  Note that in add of the properties below, the WFx driver also supports
+  `mac-address` and `local-mac-address` as described in
+  Documentation/devicetree/bindings/net/ethernet.txt

+      bindings.

+      IRQ_TYPE_EDGE_RISING are both supported by the chip and the driver. When
+      SPI is used, this property is required. When SDIO is used, the "in-band"
+      interrupt provided by the SDIO bus is used unless an interrupt is defined
+      in the Device Tree.
+    maxItems: 1
+  reset-gpios:
+    description: (SPI only) Phandle of gpio that will be used to reset chip
+      during probe. Without this property, you may encounter issues with warm
+      boot. (For legacy purpose, the gpio in inverted when compatible ==
+      "silabs,wfx-spi")
+
+      For SDIO, the reset gpio should declared using a mmc-pwrseq.

-SPI
----
-
-You have to declare the WFxxx chip in your device tree.
-
-Required properties:
- - compatible: Should be "silabs,wf200"
- - reg: Chip select address of device
- - spi-max-frequency: Maximum SPI clocking speed of device in Hz
- - interrupts-extended: Should contain interrupt line (interrupt-parent +
-   interrupt can also been used). Trigger should be `IRQ_TYPE_EDGE_RISING`.
-
-Optional properties:
- - reset-gpios: phandle of gpio that will be used to reset chip during probe.
-   Without this property, you may encounter issues with warm boot.
-   (Legacy: when compatible == "silabs,wfx-spi", the gpio is inverted.)
-
-Please consult Documentation/devicetree/bindings/spi/spi-bus.txt for optional
-SPI connection related properties,

-SDIO
-----
-
-The driver is able to detect a WFxxx chip on SDIO bus by matching its Vendor ID
-and Product ID. However, driver will only provide limited features in this
-case. Thus declaring WFxxx chip in device tree is strongly recommended (and may
-become mandatory in the future).
-
-Required properties:
- - compatible: Should be "silabs,wf200"
- - reg: Should be 1
-
-In addition, it is recommended to declare a mmc-pwrseq on SDIO host above WFx.
-Without it, you may encounter issues with warm boot. mmc-pwrseq should be
-compatible with mmc-pwrseq-simple. Please consult
-Documentation/devicetree/bindings/mmc/mmc-pwrseq-simple.txt for more
-information.
-
-Example:
-
-/ {
-	wfx_pwrseq: wfx_pwrseq {
-		compatible = "mmc-pwrseq-simple";
-		pinctrl-names = "default";
-		pinctrl-0 = <&wfx_reset>;
-		reset-gpios = <&gpio 13 GPIO_ACTIVE_LOW>;
-	};
-};
-
-&mmc1 {

-		pinctrl-names = "default";
-		pinctrl-0 = <&wfx_wakeup>;
-		wakeup-gpios = <&gpio 12 GPIO_ACTIVE_HIGH>;

-};
-
-Note that #address-size and #size shoud already be defined in node mmc1, but it
-is rarely the case.
-
-Common properties
------------------
-
-Some properties are recognized either by SPI and SDIO versions:
- - wakeup-gpios: phandle of gpio that will be used to wake-up chip. Without
-   this property, driver will disable most of power saving features.
- - config-file: Use an alternative file as PDS. Default is `wf200.pds`. Only
-   necessary for development/debug purpose.
- - slk_key: String representing hexadecimal value of secure link key to use.
-   Must contains 64 hexadecimal digits. Not supported in current version.
-
-WFx driver also supports `mac-address` and `local-mac-address` as described in
-Documentation/devicetree/bindings/net/ethernet.txt

 This is a list of things that need to be done to get this driver out of the
 staging directory.
 
-  - The HIF API is not yet clean enough.
-
-  - The code that check the corectness of received message (in rx_helper()) can
-    be improved. See:
-       https://lore.kernel.org/driverdev-devel/2302785.6C7ODC2LYm@pc-42/
-
   - As suggested by Felix, rate control could be improved following this idea:
         https://lore.kernel.org/lkml/3099559.gv3Q75KnN1@pc-42/
 
-  - Feature called "secure link" should be either developed (using kernel
-    crypto API) or dropped.
-
-  - The device allows to filter multicast traffic. The code to support these
-    filters exists in the driver but it is disabled because it has never been
-    tested.
-
-  - In wfx_cmd_send(), "async" allow to send command without waiting the reply.
-    It may help in some situation, but it is not yet used. In add, it may cause
-    some trouble:
-      https://lore.kernel.org/driverdev-devel/alpine.DEB.2.21.1910041317381.2992@hadrien/
-    So, fix it (by replacing the mutex with a semaphore) or drop it.

-	 The scrollback buffer of the standard VGA console is located in
-	 the VGA RAM.  The size of this RAM is fixed and is quite small.
-	 If you require a larger scrollback buffer, this can be placed in
-	 System RAM which is dynamically allocated during initialization.
-	 Placing the scrollback buffer in System RAM will slightly slow
-	 down the console.

-	 If you want this feature, say 'Y' here and enter the amount of

-	  switching between consoles. Otherwise, the scrollback history will be
-	  flushed each time the console is switched. This feature can also be
-	  enabled using the boot command line parameter
-	  'vgacon.scrollback_persistent=1'.
-
-	  This feature might break your tool of choice to flush the scrollback
-	  buffer, e.g. clear(1) will work fine but Debian's clear_console(1)
-	  will be broken, which might cause security issues.
-	  You can use the escape sequence \e[3J instead if this feature is
-	  activated.
-
-	  Note that a buffer of VGACON_SOFT_SCROLLBACK_SIZE is taken for each
-	  created tty device.
