* Toradex Colibri VF50 Touchscreen driver Required Properties: - compatible must be toradex,vf50-touchscreen - io-channels: adc channels being used by the Colibri VF50 module - xp-gpios: FET gate driver for input of X+ - xm-gpios: FET gate driver for input of X- - yp-gpios: FET gate driver for input of Y+ - ym-gpios: FET gate driver for input of Y- - interrupt-parent: phandle for the interrupt controller - interrupts: pen irq interrupt for touch detection - pinctrl-names: "idle", "default", "gpios" - pinctrl-0: pinctrl node for pen/touch detection state pinmux - pinctrl-1: pinctrl node for X/Y and pressure measurement (ADC) state pinmux - pinctrl-2: pinctrl node for gpios functioning as FET gate drivers - vf50-ts-min-pressure: pressure level at which to stop measuring X/Y values Example: touchctrl: vf50_touchctrl { compatible = "toradex,vf50-touchscreen"; io-channels = <&adc1 0>,<&adc0 0>, <&adc0 1>,<&adc1 2>; xp-gpios = <&gpio0 13 GPIO_ACTIVE_LOW>; xm-gpios = <&gpio2 29 GPIO_ACTIVE_HIGH>; yp-gpios = <&gpio0 12 GPIO_ACTIVE_LOW>; ym-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>; interrupt-parent = <&gpio0>; interrupts = <8 IRQ_TYPE_LEVEL_LOW>; pinctrl-names = "idle","default","gpios"; pinctrl-0 = <&pinctrl_touchctrl_idle>; pinctrl-1 = <&pinctrl_touchctrl_default>; pinctrl-2 = <&pinctrl_touchctrl_gpios>; vf50-ts-min-pressure = <200>; status = "disabled"; };
