-* HID over I2C Device-Tree bindings
-
-HID over I2C provides support for various Human Interface Devices over the
-I2C bus. These devices can be for example touchpads, keyboards, touch screens
-or sensors.
-
-The specification has been written by Microsoft and is currently available here:
-http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx
-
-If this binding is used, the kernel module i2c-hid will handle the communication
-with the device and the generic hid core layer will handle the protocol.
-
-Required properties:
-- compatible: must be "hid-over-i2c"
-- reg: i2c slave address
-- hid-descr-addr: HID descriptor address
-- interrupts: interrupt line
-
-Additional optional properties:
-
-Some devices may support additional optional properties to help with, e.g.,
-power sequencing. The following properties can be supported by one or more
-device-specific compatible properties, which should be used in addition to the
-"hid-over-i2c" string.
-
-- compatible:
- * "wacom,w9013" (Wacom W9013 digitizer). Supports:
- - vdd-supply (3.3V)
- - vddl-supply (1.8V)
- - post-power-on-delay-ms
-
-- vdd-supply: phandle of the regulator that provides the supply voltage.
-- post-power-on-delay-ms: time required by the device after enabling its regulators
- or powering it on, before it is ready for communication.
-- touchscreen-inverted-x: See touchscreen.txt
-- touchscreen-inverted-y: See touchscreen.txt
-
-Example:
-
- i2c-hid-dev@2c {
- compatible = "hid-over-i2c";
- reg = <0x2c>;
- hid-descr-addr = <0x0020>;
- interrupt-parent = <&gpx3>;
- interrupts = <3 2>;
- };
