Cypress I2C Touchpad |
|
|
|
Required properties: |
|
- compatible: must be "cypress,cyapa". |
|
- reg: I2C address of the chip. |
|
- interrupts: interrupt to which the chip is connected (see interrupt |
|
binding[0]). |
|
|
|
Optional properties: |
|
- wakeup-source: touchpad can be used as a wakeup source. |
|
- pinctrl-names: should be "default" (see pinctrl binding [1]). |
|
- pinctrl-0: a phandle pointing to the pin settings for the device (see |
|
pinctrl binding [1]). |
|
- vcc-supply: a phandle for the regulator supplying 3.3V power. |
