+* D-Link DIR-685 Touchpad
+
+This is a I2C one-off touchpad 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 touchpad device node should be placed inside an I2C bus node.
+
+Required properties:
+- compatible: must be "dlink,dir685-touchpad"
+- reg: the I2C address of the touchpad
+- interrupts: reference to the interrupt number
+
+Example:
+
+touchpad@26 {
+ compatible = "dlink,dir685-touchpad";
+ reg = <0x26>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
+};
