commit fb1c93c2e9 upstream.
Calling amdgpu_device_ip_resume_phase1() during shutdown leaves the
HW in an active state and is an unbalanced use of the IP callbacks.
Using the IP callbacks like this can lead to memory leaks, double
free and imbalanced reference counters.
Leaving the HW in an active state can lead to DMA accesses to memory now
freed by the driver.
Both is a complete no-go for driver unload so completely revert the
workaround for now.
This reverts commit f5c7e77970.

The current code does '(bpp << 4) / 16' in the MST PBN
calculation, but that is just the same as 'bpp' so the
DSC codepath achieves absolutely nothing. Fix it up so that
the fractional part of the bpp value is actually used instead
of truncated away. 64*1006 has enough zero lsbs that we can
just shift that down in the dividend and thus still manage
to stick to a 32bit divisor.
And while touching this, let's just make the whole thing more
straightforward by making the passed in bpp value .4 binary
fixed point always, instead of having to pass in different
things based on whether DSC is enabled or not.

The check for sending the vsc infopacket to the display was gated behind
PSR (Panel Self Refresh) being enabled.
The vsc infopacket also contains the colorimetry (specifically the
container color gamut) information for the stream on modern DP.
PSR is typically only supported on mobile phone eDP displays, thus this
was not getting sent for typical desktop monitors or TV screens.
This functionality is needed for proper HDR10 functionality on DP as it
wants BT2020 RGB/YCbCr for the container color space.

Fix this by mapping svm range with always mapped flag to GPU with ACCESS

There is side effect, because all GPUs have ACCESS attribute by default
on new svm range with XNACK on, the CWSR area will be mapped to all GPUs
after this change. This side effect will be fixed with Thunk change to

Mark reports that brightness is not restored after Xorg dpms screen blank.
This behavior was introduced by commit d9e865826c ("drm/amd/display:
Simplify brightness initialization") which dropped the cached backlight
value in display code, but also removed code for when the default value
read back was less than 1 nit.
Restore this code so that the backlight brightness is restored to the
correct default value in this circumstance.

We currently don't support dirty rectangles on hardware rotated modes.
So, if a user is using hardware rotated modes with PSR-SU enabled,
use PSR-SU FFU for all rotated planes (including cursor planes).

Fix pp_dpm_sclk_od and pp_dpm_mclk_od typos.
Those were defined as pp_*clk_od but used as pp_dpm_*clk_od instead.
This change removes the _dpm part.
