+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
+
