+This is a I2C one-off touchkey controller based on the Cypress Semiconductor
+CY8C214 MCU with some firmware in its internal 8KB flash. The circuit
+board inside the router is named E119921.
+The touchkey device node should be placed inside an I2C bus node.
+- compatible: must be "dlink,dir685-touchkeys"
+- reg: the I2C address of the touchkeys
+- interrupts: reference to the interrupt number
+ compatible = "dlink,dir685-touchkeys";
+ reg = <0x26>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
