| * 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>; | |
| }; |
