v2:
 * incorporated rob herring and thierry reviews
   gpio to gpios, gpio to regulator using fixed regulators
   and pwm backlight is removed, since it is controlled by
   dcs commands

v3:
 * incorporated thierry reviews
   - Added gpio polarity details for reset-gpios
   - proper naming conventions and sequence wrt panel datasheet
     (vddp-supply, iovcc-supply,
      enable-gpios, reset-gpios, dcdc-en-gpios)
v4:
 * pinctrl-names, pinctrl-0 removed, not required for
   reset-gpios

+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 at 4700000 {
+		panel at 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>;
+		};
+	};
