		Goodix GT9xx series touch controller

		The Goodix GT9xx series touch controller is connected to the host processor via
		I2C. The controller generates interrupts when the user touches the panel. The
		host controller is expected to read the touch coordinates over I2C and pass
		the coordinates to the rest of the system.

		Required properties:

		- compatible : Should be "goodix,gt9xx"
		- reg : I2C slave address of the device.
		- interrupt-parent : Parent of interrupt.
		- interrupts : Configuration of touch panel controller interrupt
		GPIO.
		- goodix,product-id : Product identification of the controller.
		- interrupt-gpios : Interrupt gpio which is to provide interrupts to
		host, same as "interrupts" node.
		- reset-gpios : Reset gpio to control the reset of chip.
		- goodix,display-coords : Display coordinates in pixels. It is a four
		tuple consisting of min x, min y, max x and
		max y values.

		Optional properties:

		- avdd-supply : Power supply needed to power up the device, this is
		for fixed voltage external regulator.
		- vdd-supply : Power supply needed to power up the device, when use
		external regulator, do not add this property.
		- vcc-i2c-supply : Power source required to power up i2c bus.
		GT9xx series can provide 1.8V from internal
		LDO, add this properties base on hardware
		design.
		- goodix,panel-coords : Panel coordinates for the chip in pixels.
		It is a four tuple consisting of min x,
		min y, max x and max y values.
		- goodix,i2c-pull-up : To specify pull up is required.
		- goodix,force-update : To specify force update is allowed.
		- goodix,enable-power-off : Power off touchscreen during suspend.
		- goodix,button-map : Button map of key codes. The number of key codes
		depend on panel.
		- goodix,cfg-data0 : Touch screen controller config data group 0. Ask vendor
		to provide that.
		Driver supports maximum six config groups. If more than one
		groups are defined, driver will select config group depending
		on hardware configuration. If only config group 0 is defined,
		it will be used for all hardware configurations.
		Touch screen controller will use its onchip default config data
		if this property is not present.
		- goodix,cfg-data1 : Touch screen controller config data group 1. Ask vendor
		to provide that.
		- goodix,cfg-data2 : Touch screen controller config data group 2. Ask vendor
		to provide that.
		- goodix,cfg-data3 : Touch screen controller config data group 3. Ask vendor
		to provide that.
		- goodix,cfg-data4 : Touch screen controller config data group 4. Ask vendor
		to provide that.
		- goodix,cfg-data5 : Touch screen controller config data group 5. Ask vendor
		to provide that.
		- goodix,fw-name : Touch screen controller firmware file name.
		- goodix,slide-wakeup : To specify slide-wakeup property is enabled or not.
		- goodix,dbl-clk-wakeup : To specify dbl-clk-wakeup property is enabled or not.
		- goodix,change-x2y : To specify change-x2y property is enabled or not.
		- goodix,driver-send-cfg : To specify driver-send-cfg property is enabled or not.
		- goodix,have-touch-key : To specify have-touch-key property is enabled or not.
		- goodix,with-pen : To specify with-pen property is enabled or not.
