-JDI model LT070ME05000 1200x1920 7" DSI Panel
-
-Required properties:
-- compatible: should be "jdi,lt070me05000"
-- vddp-supply: phandle of the regulator that provides the supply voltage
-  Power IC supply (3-5V)
-- iovcc-supply: phandle of the regulator that provides the supply voltage
-  IOVCC , power supply for LCM (1.8V)
-- enable-gpios: phandle of gpio for enable line
-  LED_EN, LED backlight enable, High active
-- reset-gpios: phandle of gpio for reset line
-  This should be 8mA, gpio can be configured using mux, pinctrl, pinctrl-names
-  XRES, Reset, Low active
-- dcdc-en-gpios: phandle of the gpio for power ic line
-  Power IC supply enable, High active
-
-Example:
-
-	dsi0: qcom,mdss_dsi@4700000 {
-		panel@0 {
-			compatible = "jdi,lt070me05000";
-			reg = <0>;
-
-			vddp-supply = <&pm8921_l17>;
-			iovcc-supply = <&pm8921_lvs7>;
-
-			enable-gpios = <&pm8921_gpio 36 GPIO_ACTIVE_HIGH>;
-			reset-gpios = <&tlmm_pinmux 54 GPIO_ACTIVE_LOW>;
-			dcdc-en-gpios = <&pm8921_gpio 23 GPIO_ACTIVE_HIGH>;
