+* Toradex Colibri VF50 Touchscreen driver
+
+Required Properties:
+- compatible must be toradex,vf50-touchscreen
+- io-channels: adc channels being used by the Colibri VF50 module
+ IIO ADC for Y-, X-, Y+, X+ connections
+- 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-
+- interrupts: pen irq interrupt for touch detection, signal from X plate
+- pinctrl-names: "idle", "default"
+- pinctrl-0: pinctrl node for pen/touch detection, pinctrl must provide
+ pull-up resistor on X+, X-.
+- pinctrl-1: pinctrl node for X/Y and pressure measurement (ADC) state pinmux
+- 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";
+ pinctrl-0 = <&pinctrl_touchctrl_idle>, <&pinctrl_touchctrl_gpios>;
+ pinctrl-1 = <&pinctrl_touchctrl_default>, <&pinctrl_touchctrl_gpios>;
+ vf50-ts-min-pressure = <200>;
+ };
