+Rockchip specific extensions to the Analogix Display Port PHY
+------------------------------------
+
+Required properties:
+- compatible : should be one of the following supported values:
+ - "rockchip.rk3288-dp-phy"
+- clocks: from common clock binding: handle to dp clock.
+ of memory mapped region.
+- clock-names: from common clock binding:
+ Required elements: "24m"
+- rockchip,grf: phandle to the syscon managing the "general register files"
+- #phy-cells : from the generic PHY bindings, must be 0;
+
+Example:
+
+edp_phy: edp-phy {
+ compatible = "rockchip,rk3288-dp-phy";
+ rockchip,grf = <&grf>;
+ clocks = <&cru SCLK_EDP_24M>;
+ clock-names = "24m";
+ #phy-cells = <0>;
