Synaptics touch controller
|
|
|
|
Required properties:
|
|
|
|
- compatible : should be "synaptics,rmi4"
|
|
- reg : i2c slave address of the device
|
|
- interrupt-parent : parent of interrupt
|
|
- interrupts : touch sample interrupt to indicate presense or release
|
|
of fingers on the panel.
|
|
- synaptics,irq-gpio : irq gpio
|
|
- synaptics,reset-gpio : reset gpio
|
|
|
|
Optional property:
|
|
- vdd-supply : Analog power supply needed to power device
|
|
- vcc_i2c-supply : Power source required to pull up i2c bus
|
|
- synaptics,i2c-pull-up : specify to indicate pull up is needed
|
|
- synaptics,button-map : virtual key code mappings to be used
|
|
- synaptics,x-flip : modify orientation of the x axis
|
|
- synaptics,y-flip : modify orientation of the y axis
|
|
- synaptics,panel-x : panel x dimension
|
|
- synaptics,panel-y : panel y dimension
|
|
- synaptics,fw-image-name : name of firmware .img file in /etc/firmware
|
|
|
|
