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)

+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";

•                   iovcc-supply = <&pm8921_lvs7>;
  

•                   enable-gpios = <&pm8921_gpio 36 GPIO_ACTIVE_HIGH>;
  

•                   reset-gpios = <&tlmm_pinmux 54 GPIO_ACTIVE_LOW>;
