+* Dialog DA9062/63 OnKey Module
+
+This module is part of the DA9062/DA9063. For more details about entire
+chips see Documentation/devicetree/bindings/mfd/da9062.txt and
+Documentation/devicetree/bindings/mfd/da9063.txt
+
+This module provides KEY_POWER, KEY_SLEEP and events.
+
+Required properties:

+- compatible: should be one of:
+ dlg,da9062-onkey
+ dlg,da9063-onkey
+
+Optional properties:
+
+ - dlg,disable-key-power : Disable power-down using a long key-press. If this
+ entry exists the OnKey driver will remove support for the KEY_POWER key
+ press. If this entry does not exist then by default the key-press
+ triggered power down is enabled and the OnKey will support both KEY_POWER
+ and KEY_SLEEP.
+
+Example:

+ pmic0: da9062@58 {
+
+ onkey {
+ compatible = "dlg,da9063-onkey";
+ dlg,disable-key-power;
+ };

+* 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>;
