FocalTech touch controller

The focaltech controller is connected to 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 "focaltech,fts_ts"

 - reg			: i2c slave address of the device, should be <0x38>; For spi interface, means cs number, always be 0

 - interrupt-parent	: parent of interrupt

 - interrupts		: irq gpio, "0x02" stands for that the irq triggered by falling edge.

 - focaltech,irq-gpio	: irq gpio, same as "interrupts" node.

 - focaltech,reset-gpio	: reset gpio

 - focaltech,num-max-touches	: maximum number of touches support

 - focaltech,display-coords 	: display resolution in pixels. A four tuple consisting of minX, minY, maxX and maxY.

Optional properties:

 - focaltech,have-key		: specify if virtual keys are supported

 - focaltech,key-number		: number of keys

 - focaltech,keys		: virtual key codes mapping to the coords

 - focaltech,key-x-coords	: constant x coordinates of keys, depends on the x resolution

 - focaltech,key-y-coords	: constant y coordinates of keys, depends on the y resolution

Example:

I2C Interface:

	i2c@f9927000 {

		focaltech@38{

			compatible = "focaltech,fts_ts";

			reg = <0x38>;

			interrupt-parent = <&msm_gpio>;

			interrupts = <13 0x02>;

			focaltech,reset-gpio = <&msm_gpio 12 0x01>;

			focaltech,irq-gpio = <&msm_gpio 13 0x02>;

			focaltech,max-touch-number = <10>;

			focaltech,display-coords =  <0 0 1080 1920>;

			pinctrl-names = "pmx_ts_active","pmx_ts_suspend","pmx_ts_release";

			pinctrl-0 = <&ts_int_active &ts_reset_active>;

			pinctrl-1 = <&ts_int_suspend &ts_reset_suspend>;

			pinctrl-2 = <&ts_release>;

			/*

			focaltech,have-key;

			focaltech,key-number = <3>;

			focaltech,keys = <139 102 158>;

			focaltech,key-x-coords = <200 600 800>;

			focaltech,key-y-coords = <2000 2000 2000>;

			interrupts = <13 0x2>;

			focaltech,reset-gpio = <&msm_gpio 12 0x01>;

			focaltech,irq-gpio = <&msm_gpio 13 0x02>;

			focaltech,max-touch-number = <10>;

			focaltech,display-coords =  <0 0 1080 1920>;

			pinctrl-names = "pmx_ts_active","pmx_ts_suspend","pmx_ts_release";

			pinctrl-0 = <&ts_int_active &ts_reset_active>;

			pinctrl-1 = <&ts_int_suspend &ts_reset_suspend>;

			pinctrl-2 = <&ts_release>;

          Allow clients to extend the available IOVA space by setting the

          DOMAIN_ATTR_GEOMETRY domain attribute. The new IOVA space created

          will be a superset of the IOVA range which was created through the

Fingerprint Cards AB. Fpc1028 driver

The fpc1028 fingerprint sensor is connected to the host processor via SPI.

The sensor will generates interrupts when the user touches the sensor.

The host controller is expected to read data over SPI and pass the data to

the rest of the system.
