Subject: [PATCH v2 0/7] Add DSI display support for QCS8300 target

This series enables the support for DSI to DP bridge port
(labeled as DSI0) of the Qualcomm's QCS8300 Ride platform.

QCS8300 SoC has DSI controller v2.5.1 and DSI PHY v4.2.
The Ride platform is having ANX7625 DSI to DP bridge chip from Analogix.
