| * Rohm BU21013 Touch Screen |
| |
| Required properties: |
| - compatible : "rohm,bu21013_tp" |
| - reg : I2C device address |
| - reset-gpios : GPIO pin enabling (selecting) chip (CS) |
| - interrupt-parent : the phandle for the gpio controller |
| - interrupts : (gpio) interrupt to which the chip is connected |
| |
| Optional properties: |
| - touch-gpios : GPIO pin registering a touch event |
| - <supply_name>-supply : Phandle to a regulator supply |
| - touchscreen-size-x : General touchscreen binding, see [1]. |
| - touchscreen-size-y : General touchscreen binding, see [1]. |
| - touchscreen-inverted-x : General touchscreen binding, see [1]. |
| - touchscreen-inverted-y : General touchscreen binding, see [1]. |
| - touchscreen-swapped-x-y : General touchscreen binding, see [1]. |
| |
| [1] All general touchscreen properties are described in |
| Documentation/devicetree/bindings/input/touchscreen/touchscreen.txt. |
| |
| Deprecated properties: |
| - rohm,touch-max-x : Maximum outward permitted limit in the X axis |
| - rohm,touch-max-y : Maximum outward permitted limit in the Y axis |
| - rohm,flip-x : Flip touch coordinates on the X axis |
| - rohm,flip-y : Flip touch coordinates on the Y axis |
