62893e9794 drm/amd/display: Remove unused duplicate register definition
[Why]

[why]
Rename hw_sequencer to hwseq.
Move all hwseq files to unique
folder hwss.

[how]
creating hwss repo in dc, and moved the dcnxx_hwseq.c
and .h files into corresponding new folders inside the hwss
and cleared the linkage errors by adding relative paths
in the Makefile.template.

79df45dc4b drm/amd/display: Don't use fsleep for PSR exit waits
[Why]
These functions can be called from high IRQ levels and the OS will hang
if it tries to use a usleep_highres or a msleep.

[How]
Replace the fsleep with a udelay.

5d72e247e5 drm/amd/display: switch DC over to the new DRM logging macros
For multi-GPU systems it is difficult to tell which GPU a particular
message is being printed for and that is undesirable because it
complicates debugging efforts. Also, the new macros allow us to enable
logging for particular parts of the codebase more selectively (since we
no longer need to throw everything at DRM_DEBUG_KMS()). So, for the
reasons outlined above we should switch to the new macros.

We can accomplish this by using the existing DC_LOGGER code to pass
around the relevant `struct drm_device` which will be fed to the new
macros in logger_types.h. Also, we must get rid of all instances of the
DC_LOG_.*() functions that are currently in amdgpu_dm since we don't use
the DC logger there and we can simply refer to the macros directly
there instead.

[WHY & HOW]
IGT's kms_hdmi_inject (subtest inject_audio) triggers a warning message
from dce_aud_az_configure. This can be fixed by checking Virtual signal

7222f5841f drm/amd/display: Use DC_LOG_DC in the trasform pixel function
[Why & How]
DC now uses a new commit sequence which is more robust since it
addresses cases where we need to reorganize pipes based on planes and
other parameters. As a result, this new commit sequence reset the DC
state by cleaning plane states and re-creating them accordingly with the
need. For this reason, the dce_transform_set_pixel_storage_depth can be
invoked after a plane state is destroyed and before its re-creation. In
this situation and on DCE devices, DC will hit a condition that will
trigger a dmesg log that looks like this:

c84ff24a77 drm/amd/display: Pass DSC slice height to PSR FW
[Why]
When DSC is enabled, the PSRSU seletive update region
must be multiple number of DSC slice height number.
The original solution is to overwrite the SU Y granularity
by DSC slice height in DAL driver. However, the size
of the SU Y granularity variable only has 8 bytes
and the DSC slice height may over the 8 bytes size.

[How]
Instead of overwriting the SU Y granularity value,
add a new DSC slice height pararmeter and pass it
to DMUB PSRSU FW. The PSRSU FW will refer to the
DSC slice height value and extend the SU region.

[Why]
Some pixel clock values could cause HDMI TMDS SSCPs to be misaligned
between different HDMI lanes when using YCbCr420 10-bit pixel format.

BIOS functions for transmitter/encoder control take pixel clock in kHz
increments, whereas the function for setting the pixel clock is in 100Hz
increments. Setting pixel clock to a value that is not on a kHz boundary
will cause the issue.

[How]
Round pixel clock down to nearest kHz in 10/12-bpc cases.

6651875ad7 drm/amd/display: Add PSR-SU-RC support in DC
[Why]

PSR-SU Rate Control - or PSR-SU-RC - enables PSR-SU panels to work with
variable refresh rate to allow for more power savings. Lowering the
refresh rate can increase PSR residency by expanding the eDP main link
shut down duration. It can also lower panel power consumption.

There is a complication with PSR, since the eDP main link can be shut
down. Therefore, the timing controller (TCON) on the eDP sink nees to be
able to scan out its remote buffer independent of the main link. To
allow the eDP source to specify the sink's refresh rate while the link
is off, vendor-specific DPCD registers are used. This allows the eDP
source to then "Rate Control" the panel during PSR active.

[How]

Add DC support to communicate with PSR-SU-RC supported eDP sinks. The
sink will need to know the desired VTotal during PSR active.

This change only adds support to DC, support in amdgpu_dm is still
pending to enable this fully.
