Alex Deucher f2ad3accef drm/amdgpu/display: only enable aux backlight control for OLED panels ... We've gotten a number of reports about backlight control not working on panels which indicate that they use aux backlight control. A recent patch: commit 2d73eabe29 Author: Camille Cho <Camille.Cho@amd.com> Date: Thu Jul 8 18:28:37 2021 +0800 drm/amd/display: Only set default brightness for OLED [Why] We used to unconditionally set backlight path as AUX for panels capable of backlight adjustment via DPCD in set default brightness. [How] This should be limited to OLED panel only since we control backlight via PWM path for SDR mode in LCD HDR panel.

The commit message seems to indicate that PWM should be used for SDR mode on HDR panels. Do something similar for backlight control in general. This may need to be revisited if and when HDR started to get used.
