| 2 | |
| 3 | Required properties: |
| 4 | - compatible : "elan,ektf2127" or "elan,ektf2132" |
| 5 | - reg : I2C slave address of the chip (0x40) |
| 6 | - interrupts : interrupt specification for the ektf2127 interrupt |
| 7 | - power-gpios : GPIO specification for the pin connected to the |
| 8 | ektf2127's wake input. This needs to be driven high |
| 9 | to take ektf2127 out of its low power state |
| 10 | |
| 11 | For additional optional properties see: touchscreen.txt |
| 12 | |
| 13 | Example: |
| 14 | |
| 15 | i2c@00000000 { |
| 16 | ektf2127: touchscreen@15 { |
| 17 | compatible = "elan,ektf2127"; |
| 18 | reg = <0x15>; |
| 19 | interrupt-parent = <&pio>; |
| 20 | interrupts = <6 11 IRQ_TYPE_EDGE_FALLING> |
| 21 | power-gpios = <&pio 1 3 GPIO_ACTIVE_HIGH>; |
| 22 | touchscreen-inverted-x; |
| 23 | touchscreen-swapped-x-y; |
| 24 | }; |
| 25 | }; |
