[v4,0/3] drm/msm/dsi: support CPHY mode for 7nm pll/phy

Message

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

v3:
 - yaml bindings
 - changed binding to "phy-type = <PHY_TYPE_DSI_CPHY>;"

v4:
 - PHY_TYPE_{DPHY,CPHY} instead of PHY_TYPE_DSI_{DPHY,CPHY}
 - use enum/default for phy-type property
 - remove a stray semicolon in dts example

Jonathan Marek (3):
  dt-bindings: msm: dsi: add missing 7nm bindings
  dt-bindings: msm: dsi: document phy-type property for 7nm dsi phy
