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 | |
