1* HID over I2C Device-Tree bindings 2 3HID over I2C provides support for various Human Interface Devices over the 4I2C bus. These devices can be for example touchpads, keyboards, touch screens 5or sensors. 6 7The specification has been written by Microsoft and is currently available here: 8http://msdn.microsoft.com/en-us/library/windows/hardware/hh852380.aspx 9 10If this binding is used, the kernel module i2c-hid will handle the communication 11with the device and the generic hid core layer will handle the protocol. 12 13Required properties: 14- compatible: must be "hid-over-i2c" 15- reg: i2c slave address 16- hid-descr-addr: HID descriptor address 17- interrupt-parent: the phandle for the interrupt controller 18- interrupts: interrupt line 19 20Example: 21 22 i2c-hid-dev@2c { 23 compatible = "hid-over-i2c"; 24 reg = <0x2c>; 25 hid-descr-addr = <0x0020>; 26 interrupt-parent = <&gpx3>; 27 interrupts = <3 2>; 28 }; 29
