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.
For v2 I rebased the series on top of v5.15-rc1. There still is a functional dependency on many different patches pulled in through the main two dependencies, vdosys0 and vdosys1, but I wasn't able to get a clean base with these patches yet so to continue improving this series in the meantime, I decided to go with v5.15-rc1 as a base. The main potential merge-conflict points of this series with other series are mtk_drm_drv.c and mtk_drm_ddp_comp.* etc. which should be easy to resolve later on.
Note: This patch series is currently tested on v5.10 and I am still working on testing it on v5.15.
