[Why]
Documentation is helpful for the community to understand our code.
This change does some high-level documentation of some DM interfaces
with DRM, and the amdgpu base driver.
[How]
An entry for AMDgpu DC has been added to Documentation/gpu/drivers.rst
TOC. amdgpu-dc.rst is created to pull in inline doc-strings, which:
- Provides an overview for "What is DM?"
- Documents AMDgpu DM lifecyle
- Documents IRQ management
- Documents atomic_check and commit_tail interfaces

[Why]
All values computed in the gamma curve after the first upperbound
clipped point will need to be clipped anyways. We can avoid
unnecessary computations and potential fixed point
overflow by instead clipping these values to 1 automatically.
[How]
Track if upper-bound clipping has been done, and clip all values after
this threshold is reached without computing the output gamma
point.

[Why]
Set gamma not working on certain planes in MPO configuration
Root cause is that video format (YUV-420) isn't allowed for IGAM where
gamma is applied.
Fix is not easy though:
1. allowing will not work because IGAM is before ICSC so RGB gamma would
be applied on YUV pixels.
2. Moving OS gamma to DGAM or RGAM resulted in weird artifacts.
Ultimately the root cause for these artifacts was due to handling end
points and the fact that YUV->RGB conversion will frequently "overshoot"
FP 1.0 value. DCE has a single end point and slope, so we would take max.
In nightlight mode, blue channel is reduced, sometimes to flat 0 line,
but red is virtually unchanged. Any "overshot" in blue will be clipped
to 1 (max R,G,B) instead of max blue value.
[How]
Fortunately, this can be fixed on DCN where we have end point and slope
for all three color channels. We cannot fix this problem on DCE.
Other things fixed:
- switch (back) to using RGAM for OS gamma instead of IGAM
- add coeffs for 709 YUV->RGB (we used RGB->YUV for both conversions)
- switch color temperature method to scaled bradford - otherwise we would
have clipping problems that caused us to switch to IGAM for OS gamma
in the first place.
- comments and some minor improvements - there are some more issues but
they will be addressed in separate commits.

This patch adds a new API to clean up the scheduler job resources. This
is primarliy needed in cases the job was created but was not queued to
the scheduler queue. Additionally with this change, the layer which
creates the scheduler job also gets to free up the job's resources and
this entails moving the dma_fence_put(finished_fence) to the drivers
ops free handler routines.

[Why]
Hardware support for Delta Color Compression (DCC) decompression is
available in DC for GFX9 but there's no way for userspace to enable
the feature.
Enabling the feature can provide improved GFX performance and
power savings in many situations.
[How]
Extend the GFX9 tiling flags to include DCC parameters. These are
logically grouped together with tiling flags even if they are
technically distinct.
This trivially maintains backwards compatibility with existing
users of amdgpu_gem_metadata. No new IOCTls or data structures are
needed to support DCC.
This patch helps expose DCC attributes to both libdrm and amdgpu_dm.

possible interference by pplib. The reason for each pp_smu interface
mapping to 1 SMU message is so we can have the sequencing of different
SMU message in dal and shared across different OS. This will also
simplify debugging as DAL owns this interaction and there's no
confusion about division of ownership.

Separate the set_hard_min_fclk_by_freq message from the
