1* D-Link DIR-685 Touchkeys
2
3This is a I2C one-off touchkey controller based on the Cypress Semiconductor
4CY8C214 MCU with some firmware in its internal 8KB flash. The circuit
5board inside the router is named E119921.

9Required properties:
10- compatible: must be "dlink,dir685-touchkeys"
11- reg: the I2C address of the touchkeys
12- interrupts: reference to the interrupt number

14Example:
15
16touchkeys@26 {
17	compatible = "dlink,dir685-touchkeys";
18	reg = <0x26>;
19	interrupt-parent = <&gpio0>;
20	interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
21};
