The clk_get_rate return 0 if something goes wrong, so it can never be
less then zero, the ret should be set a error code, otherwise the
cdn_dp_clk_enable will return 0 when it failed at clk_get_rate.
In addition, clk_get_rate() returns an "unsigned long", so use
"unsigned long" instead of "u32" is better.

Use I915_{READ,WRITE}_FW() for updating the DSPARB registers on
VLV/CHV. This is less expesive as we can grab the uncore.lock across
the entire sequence of reads and writes instead of each register
access grabbing it.
This also allows us to eliminate the dsparb lock entirely as the
uncore.lock now effectively protects the contents of the DSPARB
registers.

Optimize the plane register accesses a little bit by grabbing
the uncore lock manually across the entire pile of accesses and
using I915_READ_FW().
This helps keep the pipe update vblank evade critical section
below our 100 usec deadline, particularly with lockdep enabled.
And in general we want to keep that critical section as short
as possible as it's executed with interrupts disabled.
Not all plane updates currently happen from within the vblank evade
critical section, so we must use the irqsave/irqrestore variants
of the spinlock functions in the plane hooks.

Pull all the plane register writes closer together to avoid having
a lot of unrelated stuff in between them. This will make things more
clear once we'll grab the uncore lock around the entire bunch. Also
in the future we might even consider moving more of the register
value computation out from the plane update hooks. This should make
that easier to do.

Check that the sink really declared 12bpc support before we enable it.
This should not actually never happen since it's mandatory for HDMI
sinks to support 12bpc if they support any deep color modes. But
reality disagrees with the theory and there are actually sinks in
the wild that violate the spec.

In commit 003342a50021 ("drm/i915: Keep track of active
forcewake domains in a bitmask") I forgot to adjust the
newly introduce fw_domains_active state across reset.
This caused the assert_forcewakes_inactive to trigger
during suspend and resume if there were user held
forcewakes.
v2: Bitmask checks are required since vfuncs are not
always present.
v3: Move bitmask tracking to get/put vfunc for simplicity.

printks are slow so we should not be doing them from the vblank evade
critical section. These could explain why we sometimes seem to
blow past our 100 usec deadline.
The problem has been there ever since commit c331879ce8ea ("drm/i915:
skylake sprite plane scaling using shared scalers.") but it may not have
been readily visible until commit e1edbd44e23b ("drm/i915: Complain

of noticing it.

It looks like we were incorrectly comparing vma->node against itself
instead of the target node, when evicting for a node on systems where we
need guard pages between regions with different cache domains. As a
consequence we can end up trying to needlessly evict neighbouring nodes,
even if they have the same cache domain, and if they were pinned we
would fail the eviction.

setting the bit in the pm interrupt generation stops the interrupt going
to the guc (not sending it to the guc as the name implies). To help the
reader rename it to DISABLE_REDIRECT_TO_GUC so that we keep the bspec

We don't use the error return for anything other than reporting and
logging that there is no VBT. We can pull the logging in the function,
and remove the error status return. Moreover, if we needed the
information for something later on, we'd probably be better off storing
the bit in dev_priv, and using it where it's needed, instead of using
the error return.
While at it, improve the comments.

Use rectangle 1 as a generic plane. Existing code already sets the smart
layer bounding box size + offset. The rectangles' offsets are relative
to the bounding box, so there is no need to set R1's offset (reset value
is 0), just its size which is the same as the bounding box.

The rate of mclk depends on the use-case. If no downscaling is required,
then mclk == pxlclk is a valid option; with downscaling however, the
rate at which mclk runs determines how much a plane can be downscaled
before composition. This is a system integration + power management
issue that is more suited to firmware rather than this driver.

To make our adjustments to RPS requires taking a mutex and potentially
sleeping for an unknown duration - until we have completed our
adjustments further RPS interrupts are immaterial (they are based on
stale thresholds) and we can safely ignore them.

Currently, we sum the render and media cycles (on different engines) to
compute a percentage - but we fail to factor in the duplication into the
threshold calculations. This makes us very eager to upclock!
If we just consider the maximum busy cycles of either counter, we should
have an accurate reflection on whether there are cycles to spare to
handle the workload at this frequency.

On Baytrail, we manually calculate busyness over the evaluation interval
to avoid issues with miscaluations with RC6 enabled. However, it turns
out that the DOWN_EI interrupt generator is completely bust - it
operates in two modes, continuous or never. Neither of which are
conducive to good behaviour. Stop unmask the DOWN_EI interrupt and just
compute everything from the UP_EI which does seem to correspond to the
desired interval.
v2: Fixup gen6_rps_pm_mask() as well
v3: Inline vlv_c0_above() to combine the now identical elapsed
calculation for up/down and simplify the threshold testing

Sometimes we want to explicitly page out all available objects from igt,
i.e. call i915_gem_shrink_all() and check that subsequent operations
succeed. This adds DROP_SHRINK_ALL [0x8] to the set of flags for
debugfs/i915_drop_caches for that purpose.

We only need to clflush those cachelines that we have validated to be
read by the GPU. Userspace typically fills the batch length in
correctly, the exceptions tend to be explicit tests within igt.
v2: Use ptr_mask_bits() to make Mika happy
v3: cmd is not advanced on MI_BBE, so make sure to include an extra
dword in the clflush.

In commit 003342a50021 ("drm/i915: Keep track of active
forcewake domains in a bitmask") I forgot to adjust the
newly introduce fw_domains_active state across reset.
This caused the assert_forcewakes_inactive to trigger
during suspend and resume if there were user held
forcewakes.
v2: Bitmask checks are required since vfuncs are not
always present.
v3: Move bitmask tracking to get/put vfunc for simplicity.

The driver is already made of 5 separate source files. Move it to a
newly created directory named synopsys where more Synopsys bridge
drivers can be added later (for the DisplayPort controller for
instance).

In I915 driver, there are many places where variable name for
intel_encoder object is given as 'intel_encoder' whereas it would
make more sense to call it just 'encoder' when possible.
This patch does this cleanup in file intel_ddi.c.
PS: There are few functions where both drm_encoder and intel_encoder
are present. For such functions, this patch does nothing.

The Synopsys Designware HDMI TX Controller does not enforce register
access on platforms instanciating it. The current driver supports two
different types of memory-mapped flat register access, but in order to
support the Amlogic Meson SoCs integration, and provide a more generic
way to handle all sorts of register mapping, switch the register access
to use the regmap infrastructure.
In the case of registers that are not flat memory-mapped or do not
conform to the current driver implementation, a regmap struct can be
given in the plat_data and be used at probe or bind.
Since the AHB audio driver is only available with direct memory access,
only allow the I2S audio driver to be registered is directly
memory-mapped.

The DWC HDMI TX controller interfaces with a companion PHY. While
Synopsys provides multiple standard PHYs, SoC vendors can also integrate
a custom PHY.
Modularize PHY configuration to support vendor PHYs through platform
data. The existing PHY configuration code was originally written to
support the DWC HDMI 3D TX PHY, and seems to be compatible with the DWC
MLP PHY. The HDMI 2.0 PHY will require a separate configuration
function.

The HDMI TX controller support different PHYs whose programming
interface can vary significantly, especially with vendor PHYs that are
not provided by Synopsys. To support them, create a PHY operation
structure that can be provided by the platform glue layer. The existing
PHY handling code (limited to Synopsys PHY support) is refactored into a
set of default PHY operations that are used automatically when the
platform glue doesn't provide its own operations.

When powering the PHY up we need to wait for the PLL to lock. This is
done by polling the TX_PHY_LOCK bit in the HDMI_PHY_STAT0 register
(interrupt-based wait could be implemented as well but is likely
overkill). The bit is asserted when the PLL locks, but the current code
incorrectly waits for the bit to be deasserted. Fix it, and while at it,
replace the udelay() with a sleep as the code never runs in
non-sleepable context.
To be consistent with the power down implementation move the poll loop
to the power off function.
