...tpr_set_transparent_mode, and dropped the extra blank line from kernel-doc of drm_dp_lttpr_init, like Bjorn suggested - Picked up Abhinav's R-b tag. - Moved the lttpr_caps on stack, as suggested by Bjorn and Abhinav in the msm implementation. - Moved the msm_dp_display_lttpr_init call after msm_dp_panel_read_sink_caps, as Abhinav suggested. - Link to v4: https://lore.kernel.org/r/20250108-drm-dp-msm-add-lttpr-transparent-mode-set-v4-0-918949bc2e3a at linaro.org Changes in v4: - Picked up Dmitry's and Johan's R-b tags for the drm generic and drm msm patches. - Moved the comment about the roll-back to...

Looking at both i915 and nouveau DP drivers, both are setting the first LTTPR (if found) in transparent mode first and then in non-transparent mode, just like the DP v2.0 specification mentions in section 3.6.6.1. Being part of the standard, setting the LTTPR in a specific operation mode can be easily moved in the generic framework. So do that by adding a new helper. Then, the msm DP driver is
