Subject: [RFC PATCH 00/11] drm/msm: Add support for SM8750

Hi,

RFC or WIP: support is not yet finished because of two important
differences not yet implemented.
1. DPU_CTL_NO_LAYER_EXT: see last commit
2. SDE_MIXER_X_SRC_SEL: LM crossbar: also hardware changes requiring
   each pipe rectangle to be programmed separately in X_SRC_SEL blend
   stage. Downstream patch is bigger than above (1).

Sending this early, to gather comments or maybe find volunteers for
implementing above missing pieces. :)

The hardware catalog and DSI parts should be finished.

Best regards,
Krzysztof
