1 * D-Link DIR-685 Touchkeys
2
3 This is a I2C one-off touchkey controller based on the Cypress Semiconductor
4 CY8C214 MCU with some firmware in its internal 8KB flash. The circuit
5 board inside the router is named E119921.
6
7 The touchkey device node should be placed inside an I2C bus node.
8
9 Required properties:
10 - compatible: must be "dlink,dir685-touchkeys"
11 - reg: the I2C address of the touchkeys
12 - interrupts: reference to the interrupt number
13
14 Example:
15
16 touchkeys@26 {
17 compatible = "dlink,dir685-touchkeys";
18 reg = <0x26>;
19 interrupt-parent = <&gpio0>;
20 interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
21 };
