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>;
};
