- * D-Link DIR-685 Touchkeys
- 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.
- Required properties:
- - compatible: must be "dlink,dir685-touchkeys"
- - reg: the I2C address of the touchkeys
- - interrupts: reference to the interrupt number
- Example:
- touchkeys@26 {
- compatible = "dlink,dir685-touchkeys";
- reg = <0x26>;
- interrupt-parent = <&gpio0>;
- interrupts = <17 IRQ_TYPE_EDGE_FALLING>;
- };
