3Required 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
11Optional 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
