Subject: [PATCH v2] dt-bindings: touchscreen: Convert edt-ft5x06 to json-schema
Convert the EDT-FT5x06 to DT schema using json-schema.
Signed-off-by: Benjamin Gaignard <benjamin.gaignard@...com>

version 2:
- preserve formatting in description
- use 'const' rather than 'enum' for reg property
- fix max/min issues

-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
-
- - 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.
-
- - touchscreen-size-x : See touchscreen.txt
- - touchscreen-size-y : See touchscreen.txt
- - touchscreen-fuzz-x : See touchscreen.txt
- - touchscreen-fuzz-y : See touchscreen.txt
- - touchscreen-inverted-x : See touchscreen.txt
- - touchscreen-inverted-y : See touchscreen.txt
- - touchscreen-swapped-x-y : See touchscreen.txt
-
-Example:
- polytouch: edt-ft5x06@38 {
- compatible = "edt,edt-ft5406", "edt,edt-ft5x06";
- reg = <0x38>;
- pinctrl-names = "default";
- pinctrl-0 = <&edt_ft5x06_pins>;
- interrupt-parent = <&gpio2>;
- interrupts = <5 IRQ_TYPE_EDGE_FALLING>;
- reset-gpios = <&gpio2 6 GPIO_ACTIVE_LOW>;
- wake-gpios = <&gpio4 9 GPIO_ACTIVE_HIGH>;
- };
