    1 * Toradex Colibri VF50 Touchscreen driver
    2 
    3 Required Properties:
    4 - compatible must be toradex,vf50-touchscreen
    5 - io-channels: adc channels being used by the Colibri VF50 module
    6 - xp-gpios: FET gate driver for input of X+
    7 - xm-gpios: FET gate driver for input of X-
    8 - yp-gpios: FET gate driver for input of Y+
    9 - ym-gpios: FET gate driver for input of Y-
   10 - interrupts: pen irq interrupt for touch detection
   11 - pinctrl-names: "idle", "default", "gpios"
   12 - pinctrl-0: pinctrl node for pen/touch detection state pinmux
   13 - pinctrl-1: pinctrl node for X/Y and pressure measurement (ADC) state pinmux
   14 - pinctrl-2: pinctrl node for gpios functioning as FET gate drivers
   15 - vf50-ts-min-pressure: pressure level at which to stop measuring X/Y values
   16 
   17 Example:
   18 
   19         touchctrl: vf50_touchctrl {
   20                 compatible = "toradex,vf50-touchscreen";
