Required properties:
 - compatible		: must be "cy,cyttsp5_i2c_adapter"
 - reg			: Device I2C address or SPI chip select number
 - interrupt-parent	: the phandle for the gpio controller
			  (see interrupt binding[0]).
 - interrupts		: (gpio) interrupt to which the chip is connected
			  (see interrupt binding[0]).
 - vcc_i2c-supply	: power supply
 - vdd-supply		: power supply
 - cy,mt		: multi-touch

Optional properties:
 - cy,btn		: button
