Kernel-4.18.0-80.el8_winstar,wf35ltiac

Winstar Display Corporation 3.5” QVGA (320x240) TFT LCD panel

Required properties:

• compatible: should be “winstar,wf35ltiacd”
• power-supply: regulator to provide the VCC supply voltage (3.3 volts)

This binding is compatible with the simple-panel binding, which is specified
in simple-panel.txt in this directory.

Example:
backlight: backlight {
compatible = “pwm-backlight”;
pwms = <&hlcdc_pwm 0 50000 PWM_POLARITY_INVERTED>;
brightness-levels = <0 31 63 95 127 159 191 223 255>;
default-brightness-level = <191>;
power-supply = <&bl_reg>;
};

bl_reg: backlight_regulator {
    compatible = "regulator-fixed";
    regulator-name = "backlight-power-supply";
    regulator-min-microvolt = <5000000>;
    regulator-max-microvolt = <5000000>;
};

panel: panel {
    compatible = "winstar,wf35ltiacd", "simple-panel";
    backlight = <&backlight>;
    power-supply = <&panel_reg>;
    #address-cells = <1>;
    #size-cells = <0>;

    port {
        #address-cells = <1>;
        #size-cells = <0>;

        panel_input: endpoint {
            remote-endpoint = <&hlcdc_panel_output>;
        };
    };
};

panel_reg: panel_regulator {
    compatible = "regulator-fixed";
    regulator-name = "panel-power-supply";
    regulator-min-microvolt = <3300000>;
    regulator-max-microvolt = <3300000>;
};
