* 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
|
|
- interrupt-parent: the phandle for the interrupt controller
|
|
- interrupts: interrupt line
|
|
|
|
Example:
|
|
|
|
i2c-hid-dev@2c {
|
|
compatible = "hid-over-i2c";
|
|
reg = <0x2c>;
|
|
hid-descr-addr = <0x0020>;
|
|
interrupt-parent = <&gpx3>;
|
|
interrupts = <3 2>;
|
|
};
