[PATCH v2 2/3] dt-bindings: phy: rockchip-inno-csi-dphy: add rockchip,clk-lane-phase property

[Gerald Loacker]

Add support for the optional rockchip,clk-lane-phase device tree property
to allow board-specific tuning of the clock lane sampling phase for
improved signal integrity across supported data rates.
