+Qualcomm Technologies Inc. adreno/snapdragon eDP output
+
+Required properties:
+- compatible:
+ * "qcom,mdss-edp"
+- reg: Physical base address and length of the registers of controller and PLL
+- reg-names: The names of register regions. The following regions are required:
+ * "edp"
+ * "pll_base"
+- interrupts: The interrupt signal from the eDP block.
+- power-domains: Should be <&mmcc MDSS_GDSC>.
+- clocks: device clocks
+ See Documentation/devicetree/bindings/clocks/clock-bindings.txt for details.
+- clock-names: the following clocks are required:
+ * "core_clk"
+ * "iface_clk"
+ * "mdp_core_clk"
+ * "pixel_clk"
+ * "link_clk"
+- #clock-cells: The value should be 1.
+- vdda-supply: phandle to vdda regulator device node
+- lvl-vdd-supply: phandle to regulator device node which is used to supply power
+ to HPD receiving chip
+- panel-en-gpios: GPIO pin to supply power to panel.
+- panel-hpd-gpios: GPIO pin used for eDP hpd.
+
+
+Optional properties:
+- interrupt-parent: phandle to the MDP block if the interrupt signal is routed
+ through MDP block
+
+Example:
+ mdss_edp: qcom,mdss_edp@fd923400 {
+ compatible = "qcom,mdss-edp";
+ reg-names =
+ "edp",
+ "pll_base";
+ reg = <0xfd923400 0x700>,
+ <0xfd923a00 0xd4>;
+ interrupt-parent = <&mdss_mdp>;
+ interrupts = <12 0>;
+ power-domains = <&mmcc MDSS_GDSC>;
+ clock-names =
+ "core_clk",
+ "pixel_clk",
+ "iface_clk",
+ "link_clk",
+ "mdp_core_clk";
+ clocks =
+ <&mmcc MDSS_EDPAUX_CLK>,
+ <&mmcc MDSS_EDPPIXEL_CLK>,
+ <&mmcc MDSS_AHB_CLK>,
+ <&mmcc MDSS_EDPLINK_CLK>,
+ <&mmcc MDSS_MDP_CLK>;
+ #clock-cells = <1>;
+ vdda-supply = <&pma8084_l12>;
+ lvl-vdd-supply = <&lvl_vreg>;
+ panel-en-gpios = <&tlmm 137 0>;
+ panel-hpd-gpios = <&tlmm 103 0>;
+ };
