2024-11-04drm/amd/display: Implement new backlight_level_params structureKaitlyn Tse20-41/+119
[Why] Implement the new backlight_level_params structure as part of the VBAC framework, the information in this structure is needed to be passed down to the DMCUB to identify the backlight control type, to adjust the backlight of the panel and to perform any required conversions from PWM to nits or vice versa. [How] Modified existing functions to include the new backlight_level_params structure.

2024-11-04drm/amd/display: Don't write DP_MSTM_CTRL after LTWayne Lin1-12/+4
[Why] Observe after suspend/resme, we can't light up mst monitors under specific mst hub. The reason is that driver still writes DPCD DP_MSTM_CTRL after LT. It's forbidden even we write the same value for that dpcd register. [How] We already resume the mst branch device dpcd settings during resume_mst_branch_status(). Leverage drm_dp_mst_topology_queue_probe() to only probe the topology, not calling drm_dp_mst_topology_mgr_resume() which will set DP_MSTM_CTRL as well.

2024-10-28drm/amd/display: store sharpness 1dlut table in dscl_prog_dataSamson Tam4-4/+6
[Why] Previously dscl_prog_data stored pointer to sharpness 1dlut table. SPL had four pre-generated tables, one for each setup. This allowed us to minimize number of times we had to recalculate table when switching between setups. However, with dual display, this becomes an issue because for a given setup, we could have a different per app sharpness value than the global sharpness value. So the pre-generated table will change but both displays may point to the same table and one of them will have the wrong sharpness setting. [How] Store the sharpness 1dlut table in dscl_prog_data. This ensures that each display can have its own sharpness setting.
