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@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>;
+ };
