| Tom Rini | 53633a8 | 2024-02-29 12:33:36 -0500 | [diff] [blame] | 1 | Device tree bindings for Atmel capacitive touch device, typically |
| 2 | an Atmel touch sensor connected to AtmegaXX MCU running firmware |
| 3 | based on Qtouch library. |
| 4 | |
| 5 | The node for this device must be a child of a I2C controller node, as the |
| 6 | device communicates via I2C. |
| 7 | |
| 8 | Required properties: |
| 9 | |
| 10 | compatible: Must be "atmel,captouch". |
| 11 | reg: The I2C slave address of the device. |
| 12 | interrupts: Property describing the interrupt line the device |
| 13 | is connected to. The device only has one interrupt |
| 14 | source. |
| 15 | linux,keycodes: Specifies an array of numeric keycode values to |
| 16 | be used for reporting button presses. The array can |
| 17 | contain up to 8 entries. |
| 18 | |
| 19 | Optional properties: |
| 20 | |
| 21 | autorepeat: Enables the Linux input system's autorepeat |
| 22 | feature on the input device. |
| 23 | |
| 24 | Example: |
| 25 | |
| 26 | atmel-captouch@51 { |
| 27 | compatible = "atmel,captouch"; |
| 28 | reg = <0x51>; |
| 29 | interrupt-parent = <&tlmm>; |
| 30 | interrupts = <67 IRQ_TYPE_EDGE_FALLING>; |
| 31 | linux,keycodes = <BTN_0>, <BTN_1>, |
| 32 | <BTN_2>, <BTN_3>, |
| 33 | <BTN_4>, <BTN_5>, |
| 34 | <BTN_6>, <BTN_7>; |
| 35 | autorepeat; |
| 36 | }; |
