* 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
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
ft6x06@38 {

|
||
|
|
touchscreen-inverted-x;
|
||
|
|
touchscreen-swapped-x-y;
|
||
|
|
};
