9543a9c3e2 drm/amd/display: Possible divide by zero in set_speed()
If "speed" is zero then we use it as a divisor to find "prescale".  It's
better to move the check for zero to the very start of the function.

a5437e0b81 drm/amd/display: clean up a condition in dmub_psr_copy_settings()
We can remove the NULL check for "res_ctx" and
"res_ctx->pipe_ctx[i].stream->link".  Also it's nicer to align the
conditions using spaces so I re-indented a bit.

Longer explanation: The "res_ctx" pointer points to an address in the
middle of a struct so it can't be NULL.  For
"res_ctx->pipe_ctx[i].stream->link" we know that it is equal to "link"
and "link" is non-NULL.

As long as pipe_ctx is not NULL, the address of members in this struct
cannot be NULL, which means these checks will always evaluate to false.

8144148f3d drm/amd/display: update scaling filters
Currently there is a minor error in scaling filter coefficients
caused by truncation to fit the HW registers.This error accummulates
with increased taps, but has gone unnoticed due to vast majority of
scaling being done with only 4 taps.

Scaling filters are now updated using HW team's filter generator
which has quantization error minimization built in.

f42ea55be1 drm/amd/display: add separate of private hwss functions

Some function pointers in the hwss function pointer table are
meant to be hw sequencer entry points to be called from dc.

However some of those function pointers are not meant to
be entry points, but instead used as a code reuse/inheritance
tool called directly by other hwss functions, not by dc.

Therefore, we want a more clear separation of which functions
we determine to be interface functions vs the functions we
use within hwss.

[How]
DC interface functions will be stored in:
    struct hw_sequencer_funcs
Functions used within HWSS will be stored in:
    struct hwseq_private_funcs

5ed78cd69a drm/amd/display: set MSA MISC1 bit 6 while sending colorimetry in VSC SDP
[Why]
It is confusing to sinks if we send VSC SDP only on some format. Today we
signal colorimetry format using MSA while in formats like sRGB.
But when we switch to BT2020 we set the bit to ignore MSA  colorimetry and
instead use the colorimetry information in the VSC SDP.

But if sink supports signaling of colorimetry via VSC SDP we should always
set the MSA MISC1 bit 6, instead of doing so selectively.

[How]
If sink supports signaling of colorimetry via VSC SDP, and we are sending
the colorimetry info via VSC SDP with packet revision 05h, then always
set MSA MISC1 bit 6.

1. defer delay and sw start delay has been mixed up, defer delay was
programmed to AUX_SW_CONTROL:AUX_SW_START_DELAY.
2. There's no delay for defer

[how]
1. Set  aux sw start to 0
2. Add delay for defer scenario

15caeabc57 drm/amd/display: wait for set pipe mcp command completion
[Why]
When the driver sends a pipe set command to the DMCU FW, it does not wait
for the command to complete. This can lead to unpredictable behavior if,
for example, the driver were to request a pipe disable to the FW via MCP,
then power down some hardware before the firmware has completed processing
the command.

[How]
Wait for the DMCU FW to finish processing set pipe commands

119630061e drm/amd/display: remove hw access from dc_destroy
[why]
dc_destroy should only clean up SW, this is because GPUs may be
removed before driver unload, leading to HW to be unavailable.

[how]
remove GPIO close as part of GPIO destroy, this is unnecessary because
GPIO is not shared, and GPIOs are generally closed after being opened

Add tracking to HW access during destructor to make future issues
easier to pinpoint, and block access to prevent hangs.

[Why]
The register LVTMA_PWRSEQ_CNTL is used to determine the power state of the

so during power down we think that this display is already off, so we skip
calling into VBIOS to actually turn it off.

e25228b02e drm/amd/display: Increase Backlight Gain Step Size
[Why]
Some backlight tests fail due to backlight settling
taking too long. This happens because the step
size used to change backlight levels is too small.

[How]
1. Change the size of the backlight gain step size
2. Change how DMCU firmware gets the step size value
   so that it is passed in by driver during DMCU initn

Pull drm updates from Dave Airlie:
 "This has two exciting community drivers for ARM Mali accelerators.
  Since ARM has never been open source friendly on the GPU side of the
  house, the community has had to create open source drivers for the
  Mali GPUs. Lima covers the older t4xx and panfrost the newer 6xx/7xx
  series. Well done to all involved and hopefully this will help ARM
  head in the right direction.

  There is also now the ability if you don't have any of the legacy
  drivers enabled (pre-KMS) to remove all the pre-KMS support code from
  the core drm, this saves 10% or so in codesize on my machine.

  i915 also enable Icelake/Elkhart Lake Gen11 GPUs by default, vboxvideo
  moves out of staging.

  There are also some rcar-du patches which crossover with media tree
  but all should be acked by Mauro.

[How]
Make dce_aux_transfer_raw return the operation result

Make dce_aux_transfer_with_retries delay with udelay instead
of msleep, and only on invalid reply.  Also fail on the second
invalid reply, third timeout, or first of any other error

Convert return values to drm error codes in amdgpu_dm

As the two aux transfer functions are now noticeably

dcf1a98867 drm/amd/display: Fix exception from AUX acquire failure
[Why]
AUX arbitration occurs between SW and FW components.
When AUX acquire fails, it causes engine->ddc to be NULL,
which leads to an exception when we try to release the AUX
engine.

[How]
When AUX engine acquire fails, it should return from the
function without trying to continue the operation.
The upper level will determine if it wants to retry.
i.e. dce_aux_transfer_with_retries will be used and retry.
