Merge branch 'msm-next-lumag' into HEAD

Merge display-related changes targeting Qualcomm DRM MSM driver. Notable changes: 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 Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org>
