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>;

		};

	};
