Some OEMs support custom brightness curves where the ATIF method includes
a collection of data points where the input signal is mapped out to
percentage of luminance. This series shuffles around some code to add in
the ability to do that mapping in amdgpu_dm when brightness is set.
Mario Limonciello (5):
drm/amd: Copy entire structure in amdgpu_acpi_get_backlight_caps()
drm/amd: Pass luminance data to amdgpu_dm_backlight_caps
drm/amd/display: Avoid operating on copies of backlight caps
drm/amd/display: Add support for custom brightness curve
drm/amd/display: Add a new dcdebugmask to allow turning off brightness
curve
