    1 * Pixcir I2C touchscreen controllers
    2 
    3 Required properties:
    4 - compatible: must be "pixcir,pixcir_ts" or "pixcir,pixcir_tangoc"
    5 - reg: I2C address of the chip
    6 - interrupts: interrupt to which the chip is connected
    7 - attb-gpio: GPIO connected to the ATTB line of the chip
    8 - touchscreen-size-x: horizontal resolution of touchscreen (in pixels)
    9 - touchscreen-size-y: vertical resolution of touchscreen (in pixels)
   10 
   11 Optional properties:
   12 - reset-gpios: GPIO connected to the RESET line of the chip
   13 - enable-gpios: GPIO connected to the ENABLE line of the chip
   14 - wake-gpios: GPIO connected to the WAKE line of the chip
   15 
   16 Example:
   17 
   18         i2c@00000000 {
   19                 /* ... */
   20 
   21                 pixcir_ts@5c {
   22                         compatible = "pixcir,pixcir_ts";
   23                         reg = <0x5c>;
   24                         interrupts = <2 0>;
   25                         attb-gpio = <&gpf 2 0 2>;
   26                         touchscreen-size-x = <800>;
   27                         touchscreen-size-y = <600>;
   28                 };
   29 
   30                 /* ... */
   31         };
