Required properties:
|
|
- compatible: must be "sis,9200-ts"
|
|
- reg: i2c slave address
|
|
- interrupt-parent: the phandle for the interrupt controller
|
|
(see interrupt binding [0])
|
|
- interrupts: touch controller interrupt (see interrupt
|
|
binding [0])
|
|
|
|
Optional properties:
|
|
- pinctrl-names: should be "default" (see pinctrl binding [1]).
|
|
- pinctrl-0: a phandle pointing to the pin settings for the
|
