[PATCH 0/4] drm/msm/dp: Add support for SC8180x eDP controller
by Bjorn Andersson 09 Jun '21

09 Jun '21

The first patch in the series is somewhat unrelated to the support, but simplifies reasoning and debugging of timing related issues. The second patch introduces support for dealing with different register block layouts, which is used in the forth patch to describe the hardware blocks found in the SC8180x eDP block. The third patch configures the INTF_CONFIG register, which carries the configuration for widebus handling. As with the DPU the bootloader enables widebus and we need to disable it, … [View More]

[v4 0/4] drm: Support basic DPCD backlight in panel-simple and add a new panel ATNA33XC20
by Rajeev Nandan 08 Jun '21

08 Jun '21

This series adds the support for the eDP panel that needs the backlight controlling over the DP AUX channel using DPCD registers of the panel as per the VESA's standard. This series also adds support for the Samsung eDP AMOLED panel that needs DP AUX to control the backlight, and introduces new delays in the @panel_desc.delay to support this panel. This patch series depends on the following two series: - Doug's series [1], exposed the DP AUX channel to the panel-simple. - Lyude's series [2], … [View More]

[PATCH 0/9] Prereqs for TTM accelerated migration
by Thomas Hellström 08 Jun '21

08 Jun '21

A couple of patches from Chris which implement pipelined migration and clears by atomically writing the PTEs in place before performing the actual blit. Some ww utilities mainly for the accompanying selftests added by Thomas, as well as modified the above patches for ww locking- and lmem support. The actual hook up to the i915 ttm backend is being worked on and not included yet, so this is considered to be an early review opportunity.

[PATCH] drm/stm: Remove usage of drm_display_mode_to_videomode()
by Marek Vasut 08 Jun '21

08 Jun '21

There is not much value in the extra conversion step, the calculations required for the LTDC IP are different than what is used in the drm_display_mode_to_videomode(), so just do the right ones in the LTDC driver right away.
