[PATCH v1] drm/msm: add support for 2.4.1 DSI version for sc7180 soc

From: Harigovindan P
Date: Fri Nov 29 2019 - 02:05:21 EST


Changes in v1:
-Modify commit text to indicate DSI version and SOC detail(Jeffrey Hugo).
-Splitting visionox panel driver code out into a
different patch(set), since panel drivers are merged into
drm-next via a different tree(Rob Clark).
