-FocalTech EDT-FT5x06 Polytouch driver
-=====================================
-
-There are 5 variants of the chip for various touch panel sizes
-FT5206GE1  2.8" .. 3.8"
-FT5306DE4  4.3" .. 7"
-FT5406EE8  7"   .. 8.9"
-FT5506EEG  7"   .. 8.9"
-FT5726NEI  5.7” .. 11.6"
-
-The software interface is identical for all those chips, so that
-currently there is no need for the driver to distinguish between the
-different chips. Nevertheless distinct compatible strings are used so
-that a distinction can be added if necessary without changing the DT
-bindings.
-
-
-Required properties:
- - compatible:  "edt,edt-ft5206"
-           or:  "edt,edt-ft5306"
-           or:  "edt,edt-ft5406"
-           or:  "edt,edt-ft5506"
-           or:  "evervision,ev-ft5726"
-           or:  "focaltech,ft6236"
-
- - reg:         I2C slave address of the chip (0x38)
- - interrupts:       interrupt specification for the touchdetect
-                     interrupt
-
-Optional properties:
- - reset-gpios: GPIO specification for the RESET input
- - wake-gpios:  GPIO specification for the WAKE input
- - vcc-supply:  Regulator that supplies the touchscreen
-
- - pinctrl-names: should be "default"
- - pinctrl-0:   a phandle pointing to the pin settings for the
-                control gpios
-
- - wakeup-source: If present the device will act as wakeup-source
-
- - threshold:   allows setting the "click"-threshold in the range
-                from 0 to 80.
-
- - gain:        allows setting the sensitivity in the range from 0 to
-                31. Note that lower values indicate higher
-                sensitivity.
-
- - offset:      allows setting the edge compensation in the range from
-                0 to 31.
-
- - offset-x:    Same as offset, but applies only to the horizontal position.
-                Range from 0 to 80, only supported by evervision,ev-ft5726
-                devices.
-
- - offset-y:    Same as offset, but applies only to the vertical position.
-                Range from 0 to 80, only supported by evervision,ev-ft5726
-                devices.

-		reg = <0x38>;
-		pinctrl-names = "default";

-		interrupt-parent = <&gpio2>;
-		interrupts = <5 IRQ_TYPE_EDGE_FALLING>;
-		reset-gpios = <&gpio2 6 GPIO_ACTIVE_LOW>;
-		wake-gpios = <&gpio4 9 GPIO_ACTIVE_HIGH>;
