* ChipOne icn8318 I2C touchscreen controller |
|
|
|
Required properties: |
|
- compatible : "chipone,icn8318" |
|
- reg : I2C slave address of the chip (0x40) |
|
- interrupts : interrupt specification for the icn8318 interrupt |
|
- wake-gpios : GPIO specification for the WAKE input |
|
- touchscreen-size-x : horizontal resolution of touchscreen (in pixels) |
|
- touchscreen-size-y : vertical resolution of touchscreen (in pixels) |
|
|
|
Optional properties: |
|
- pinctrl-names : should be "default" |
|
- pinctrl-0: : a phandle pointing to the pin settings for the |
|
control gpios |
|
- 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 |
|
|
|
