DPU, DSI, MDSS:
- Support for SM8350, SM8450 SM8550 and SC8280XP platform

Core:
- Added bindings for SM8150 (driver support already present)

DPU:
- Partial support for DSC on SM8150 and SM8250
- Fixed color transformation matrix being lost on suspend/resume

DP:
- Support for DP on SDM845 and SC8280XP platforms
- HPD fixes
- Support for limiting DP link rate via DT property, this enables
  support for HBR3 rates.

DSI:
- Validate display modes according to the DSI OPP table
- DSI PHY support for the SM6375 platform
- Fixed byte intf clock selection for 14nm PHYs

MDP5:
- Schema conversion to YAML

Misc fixes as usual
