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

+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)
+- dcdc_en-supply: phandle of the regulator that provides the supply voltage
+ Power IC supply enable, High active
+- vcc-supply: phandle of the regulator that provides the supply voltage
+ IOVCC , power supply for LCM (1.8V)
+- 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
+- enable-gpios: phandle of gpio for enable line
+ LED_EN, LED backlight enable, High active
+
+Example:
+
+ vcc_1p8v: regulator-fixed@2 {
+ compatible = "regulator-fixed";
+ regulator-min-microvolt = <1800000>;
+ regulator-max-microvolt = <1800000>;
+ regulator-name = "vcc_1p8v";
+ regulator-type = "voltage";
+ startup-delay-us = <0>;
+ gpio = <&pm8921_gpio 23 GPIO_ACTIVE_HIGH>;
+ enable-active-high;
+ regulator-boot-on;
+ };
+
+ tlmm_pinmux: pinctrl@800000 {
+
+ dsi_panel_pinctrl: dsi-panel-pinctrl {
+ mux {
+ pins = "gpio54";
+ function = "gpio";
+ bias-pull-up;
+ drive-strength = <8>;
+ };
+ };
+ };
+
+ dsi0: qcom,mdss_dsi@4700000 {
+ panel@0 {
+ compatible = "jdi,lt070me05000";
+ reg = <0>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&dsi_panel_pinctrl>;
+
+ vddp-supply = <&pm8921_l17>;
+ dcdc_en-supply = <&pm8921_lvs7>;
+ vcc-supply = <&vcc_1p8v>;
+
+ reset-gpios = <&tlmm_pinmux 54 0>;
+ enable-gpios = <&pm8921_gpio 36 GPIO_ACTIVE_HIGH>;
+ };
+ };
