| 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 | }; |
