This adds support for the D-Link DIR-685 touchkeys found in the router with this name. The vendor code calles this a "touchpad" but we are registering it here under its real name.

* 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>;
|
|
};
