3Required properties:
4- compatible:
5 * "qcom,mdss-edp"
6- reg: Physical base address and length of the registers of controller and PLL
7- reg-names: The names of register regions. The following regions are required:
8 * "edp"
9 * "pll_base"
10- interrupts: The interrupt signal from the eDP block.
11- power-domains: Should be <&mmcc MDSS_GDSC>.
12- clocks: device clocks
13 See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
14- clock-names: the following clocks are required:
15 * "core"
16 * "iface"
17 * "mdp_core"
18 * "pixel"
19 * "link"
20- #clock-cells: The value should be 1.
21- vdda-supply: phandle to vdda regulator device node
22- lvl-vdd-supply: phandle to regulator device node which is used to supply power
23 to HPD receiving chip
24- panel-en-gpios: GPIO pin to supply power to panel.
25- panel-hpd-gpios: GPIO pin used for eDP hpd.
