Hi everyone,
this series is built around the DisplayPort driver. The dpi/dpintf driver and the added helper functions are required for the DisplayPort driver to work.
It is version 1 of the patch series following the RFC version: https://lore.kernel.org/linux-mediatek/20210816192523.1739365-1-msp@baylibre...
Note: This patch series is currently tested on v5.10 and I am currently working on testing it on v5.14.
The series is now based on these patch series and its dependencies: - Add Mediatek Soc DRM (vdosys0) support for mt8195 https://lore.kernel.org/linux-mediatek/20210825144833.7757-1-jason-jh.lin@me... - Add MediaTek SoC DRM (vdosys1) support for mt8195 https://lore.kernel.org/linux-mediatek/20210825100531.5653-1-nancy.lin@media...
Changes in v1: - Added DP binding documentation. - Addressed feedback from the RFC. - General cleanups in DPI and DP drivers. - See individual patches for details on the changes done.
Thanks in advance for any feedback and comments.
Best, Markus
