+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>;

+                       iovcc-supply = <&pm8921_lvs7>;
+
+                       enable-gpios = <&pm8921_gpio 36 GPIO_ACTIVE_HIGH>;
+                       reset-gpios = <&tlmm_pinmux 54 GPIO_ACTIVE_LOW>;
