Subject: [PATCH v2 0/2] drm/msm/dsi: support CPHY mode for 7nm pll/phy

Add the required changes to support 7nm pll/phy in CPHY mode.

This adds a "qcom,dsi-phy-cphy-mode" property for the PHY node to enable
the CPHY mode.

v2:
 - rebased on DSI PHY reworks
 - reworked getting cphy_mode in dsi_host.c
 - documentation change in separate patch
