Maxim STI touch controller:
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- spi-max-frequency: Maximum SPI frequency supported by the controller.
|
||
|
|
- avdd-supply: analog power supply.
|
||
|
|
- dvdd-supply: digial power supply.
|
||
|
|
- maxim_sti,irq-gpio: irq gpio.
|
||
|
|
- maxim_sti,reset-gpio: reset gpio.
|
||
|
|
- maxim_sti,touch_fusion: path to touch_fusion daemon.
|
||
|
|
- maxim_sti,config_file: path to config file.
|
||
|
|
- maxim_sti,fw_name: name of firmware file.
|
||
|
|
|
||
|
|
Optional properties:
|
||
|
|
- pinctrl-names : this should be defined if a target uses pinctrl framework.
|
||
|
|
See "pinctrl" in documentation/devicetree/bindings/pinctrl/msm-pinctrl.txt.
|
||
|
|
It should specify the names of the configs that pinctrl can install in driver.
|
||
|
|
Following are the pinctrl configs that can be installed:
|
||
|
|
"pmx_ts_active" : active configuration of pins. This should specify active
|
||
|
|
config defined in pin groups of interrupt and reset gpios.
|
||
|
|
"pmx_ts_suspend" : disabled configuration of pins. This should specify sleep
|
||
|
|
config defined in pin groups of interrupt and reset gpios.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
&spi_13 { /* BLSP1 QUP3 */
|
