-STMicroelectronics touch controller
-
-The STMicroelectronics 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 "st,fts".
- - reg : i2c slave address of the device.
- - interrupt-parent : parent of interrupt.
- - interrupts : touch sample interrupt to indicate presense or release
- of fingers on the panel.
- - vdd-supply : Power supply needed to power up the device.
- - vcc-supply : Power source required to power up i2c bus.
- - st,irq-gpio : irq gpio which is to provide interrupts to host,
- same as "interrupts" node. It will also
- contain active low or active high information.
- - st,reset-gpio : reset gpio to control the reset of chip.
- - pinctrl-names : This should be defined if a target uses pinctrl framework.
- See "pinctrl" in Documentation/devicetree/bindings/pinctrl/msm-pinctrl.txt.
- Specify the names of the configs that pinctrl can install in driver.
- Following are the pinctrl configs that can be installed:
- "pmx_ts_active" : Active configuration of pins, this should specify active
- config defined in pin groups of interrupt and reset gpio.
- "pmx_ts_suspend" : Disabled configuration of pins, this should specify sleep
- config defined in pin groups of interrupt and reset gpio.
- "pmx_ts_release" : Release configuration of pins, this should specify
- release config defined in pin groups of interrupt and reset gpio.
- - st,regulator_avdd : name of Power supply needed to power up the device.
- - st,regulator_dvdd : name of Power source required to power up i2c bus.
-Optional properties:

-Example:
- i2c@78b9000 { /* BLSP1 QUP5 */
- st_fts@49 {
- compatible = "st,fts";
- reg = <0x49>;
- interrupt-parent = <&msm_gpio>;
- interrupts = <13 0x2008>;
- vdd-supply = <&pm8916_l17>;
- vcc-supply = <&pm8916_l6>;
- pinctrl-names = "pmx_ts_active","pmx_ts_suspend";
- pinctrl-0 = <&ts_int_active &ts_reset_active>;
- pinctrl-1 = <&ts_int_suspend &ts_reset_suspend>;
- st,irq-gpio = <&msm_gpio 13 0x00000001>;
- st,reset-gpio = <&msm_gpio 12 0x0>;
- st,regulator_dvdd = "vdd";
- st,regulator_avdd = "avdd";
