1 | * FocalTech FT6236 I2C touchscreen controller |
| 2 | ||
| 3 | Required properties: | |
| 4 | - compatible : "focaltech,ft6236" | |
| 5 | - reg : I2C slave address of the chip (0x38) | |
| 6 | - interrupt-parent : a phandle pointing to the interrupt controller | |
| 7 | serving the interrupt for this chip | |
| 8 | - interrupts : interrupt specification for the touch controller | |
| 9 | interrupt | |
| 10 | - reset-gpios : GPIO specification for the RSTN input | |
| 11 | - touchscreen-size-x : horizontal resolution of touchscreen (in pixels) | |
| 12 | - touchscreen-size-y : vertical resolution of touchscreen (in pixels) | |
| 13 | ||
| 14 | Optional properties: | |
| 15 | - touchscreen-fuzz-x : horizontal noise value of the absolute input | |
| 16 | device (in pixels) | |
| 17 | - touchscreen-fuzz-y : vertical noise value of the absolute input | |
| 18 | device (in pixels) | |
| 19 | - touchscreen-inverted-x : X axis is inverted (boolean) | |
| 20 | - touchscreen-inverted-y : Y axis is inverted (boolean) | |
| 21 | - touchscreen-swapped-x-y: X and Y axis are swapped (boolean) | |
| 22 | Swapping is done after inverting the axis | |
| 23 | ||
| 24 | Example: | |
| 25 | ||
| 26 | ft6x06@38 { | |
| 27 | compatible = "focaltech,ft6236"; | |
| 28 | reg = <0x38>; | |
| 29 | interrupt-parent = <&gpio>; | |
| 30 | interrupts = <23 2>; | |
| 31 | touchscreen-size-x = <320>; | |
| 32 | touchscreen-size-y = <480>; | |
| 33 | touchscreen-inverted-x; | |
| 34 | touchscreen-swapped-x-y; | |
| 35 | }; |
