Subject: [PATCH v2] dt-bindings: input: microchip,cap11xx: Convert txt bindings to yaml
Convert binding for the Microchip CAP11xx series HW to the YAML syntax.
Signed-off-by: David Heidelberg <david@...t.cz>

v2:
- changed mail to robh (original author seems to be not actively
maintaining the driver since 2015)
- common.yaml path fixed
- $ref input.yaml added

-Device tree bindings for Microchip CAP11xx based capacitive touch sensors
-
-The node for this device must be a child of a I2C controller node, as the
-device communication via I2C only.
-
-Required properties:
-
- compatible: Must contain one of:
- "microchip,cap1106"
- "microchip,cap1126"
- "microchip,cap1188"
-
- reg: The I2C slave address of the device.
-
- interrupts: Property describing the interrupt line the
- device's ALERT#/CM_IRQ# pin is connected to.
- The device only has one interrupt source.
-
-Optional properties:
-
- autorepeat: Enables the Linux input system's autorepeat
- feature on the input device.
-
- microchip,sensor-gain: Defines the gain of the sensor circuitry. This
- effectively controls the sensitivity, as a
- smaller delta capacitance is required to
- generate the same delta count values.
- Valid values are 1, 2, 4, and 8.
- By default, a gain of 1 is set.
-
- microchip,irq-active-high: By default the interrupt pin is active low
- open drain. This property allows using the active
- high push-pull output.
-
- linux,keycodes: Specifies an array of numeric keycode values to
- be used for the channels. If this property is
- omitted, KEY_A, KEY_B, etc are used as
- defaults. The array must have exactly six
- entries.
-
-Example:
-
-i2c_controller {
- cap1106@28 {
- compatible = "microchip,cap1106";
- interrupt-parent = <&gpio1>;
- interrupts = <0 0>;
- reg = <0x28>;
- autorepeat;
- microchip,sensor-gain = <2>;
-
- linux,keycodes = <103>, /* KEY_UP */
- <106>, /* KEY_RIGHT */
- <108>, /* KEY_DOWN */
- <105>, /* KEY_LEFT */
- <109>, /* KEY_PAGEDOWN */
- <104>; /* KEY_PAGEUP */
-

- #size-cells = <0>;

- label = "cap11xx:green:usr0";
- reg = <0>;
- };
-
- usr@1 {
- label = "cap11xx:green:usr1";
- reg = <1>;
- };
-
- alive@2 {
- label = "cap11xx:green:alive";
- reg = <2>;
- linux,default_trigger = "heartbeat";
- };
