<title>drm/amd/display: fix issues with driver unload</title>

Currently, we run into a number of WARN()s when attempting to unload the
amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from
calling drm_encoder_cleanup() too early. So, to fix this we can stop
calling drm_encoder_cleanup() from amdgpu_dm_fini() and instead have it
be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free
in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly
allocated by the slab allocator.

Code in get_output_color_space depends on knowing the pixel encoding to
determine whether to pick between eg. COLOR_SPACE_SRGB or
COLOR_SPACE_YCBCR709 for transparent RGB -&gt; YCbCr 4:4:4 in the driver.

v2: Fixed patch being accidentally based on a personal feature branch, oops!

<title>drm/amd/display: Fix set scaling doesn's work</title>

<id>040625ab82ce6dca7772cb3867fe5c9eb279a344</id>
<content type='text'>
[Why]
Setting scaling does not correctly update CRTC state. As a result
dc stream state's src (composition area) &amp;&amp; dest (addressable area)
was not calculated as expected. This causes set scaling doesn's work.

[How]
Correctly update CRTC state when setting scaling property.

Pull ACPI fixes from Rafael Wysocki:
 "These are new ACPI IRQ override quirks, low-power S0 idle (S0ix)
  support adjustments and ACPI backlight handling fixes, mostly for
  platforms using AMD chips.

  Specifics:

   - Add ACPI IRQ override quirks for Asus ExpertBook B2502, Lenovo
     14ALC7, and XMG Core 15 (Hans de Goede, Adrian Freund, Erik
     Schumacher).

   - Adjust ACPI video detection fallback path to prevent
     non-operational ACPI backlight devices from being created on
     systems where the native driver does not detect a suitable panel
     (Mario Limonciello).

   - Fix Apple GMUX backlight detection (Hans de Goede).

   - Add a low-power S0 idle (S0ix) handling quirk for HP Elitebook 865
     and stop using AMD-specific low-power S0 idle code path for systems
     with Rembrandt chips and newer (Mario Limonciello)"

On desktop APUs amdgpu doesn't create a native backlight device
as no eDP panels are found.  However if the BIOS has reported
backlight control methods in the ACPI tables then an acpi_video0
backlight device will be made 8 seconds after boot.

This has manifested in a power slider on a number of desktop APUs
ranging from Ryzen 5000 through Ryzen 7000 on various motherboard
manufacturers. To avoid this, report to the acpi video detection
that the system does not have any panel connected in the native
driver.
