| * FocalTech FT6236 I2C touchscreen controller |
| |
| Required properties: |
| - compatible : "focaltech,ft6236" |
| - reg : I2C slave address of the chip (0x38) |
| - interrupt-parent : a phandle pointing to the interrupt controller |
| serving the interrupt for this chip |
| - interrupts : interrupt specification for the touch controller |
| interrupt |
| - reset-gpios : GPIO specification for the RSTN input |
| - touchscreen-size-x : horizontal resolution of touchscreen (in pixels) |
| - touchscreen-size-y : vertical resolution of touchscreen (in pixels) |
| |
| Optional properties: |
| - touchscreen-fuzz-x : horizontal noise value of the absolute input |
| device (in pixels) |
| - touchscreen-fuzz-y : vertical noise value of the absolute input |
| device (in pixels) |
| - touchscreen-inverted-x : X axis is inverted (boolean) |
| - touchscreen-inverted-y : Y axis is inverted (boolean) |
| - touchscreen-swapped-x-y: X and Y axis are swapped (boolean) |
| Swapping is done after inverting the axis |
| |
