WFX Linux driver parameters are accessible under /sys/module/wfx/parameters/

sudo tree /sys/module/wfx/parameters/

/sys/module/wfx/parameters/
├── gpio_reset
├── gpio_wakeup
└── power_mode

Each parameter can be checked

sudo cat /sys/module/wfx/parameters/gpio_reset
-2
sudo cat /sys/module/wfx/parameters/gpio_wakeup
-2
sudo cat /sys/module/wfx/parameters/power_mode
0

These parameters match those listed in the modinfo wfx parameters description

parm: gpio_reset:gpio number for reset. -1 for none. (int)
parm: gpio_wakeup:gpio number for wakeup. -1 for none. (int)
parm: power_mode:Force power save mode. 0: Disabled, 1: Allow doze, 2: Allow quiescent (int)

Possible values

• -2 (default): use values set in device tree
• -1: none (GPIO unused)
• any positive value: GPIO number as it would be set in the device tree

To check which GPIOs are currently allocated, use sudo cat /sys/kernel/debug/gpio

Typical result when using WF(M)200 in SPI mode

GPIOs 0-53, platform/3f200000.gpio, pinctrl-bcm2835:
 gpio-12 ( |wakeup ) out lo
 gpio-13 ( |reset ) out hi
GPIOs 100-101, platform/soc:virtgpio, brcmvirt-gpio, can sleep:
 gpio-100 ( |? ) out lo

Typical result when using WF(M)200 in SDIO mode

gpiochip0: GPIOs 0-53, parent: platform/3f200000.gpio, pinctrl-bcm2835:
 gpio-12  (                    |wakeup              ) out lo
 gpio-13  (                    |reset               ) out hi

gpiochip2: GPIOs 100-101, brcmvirt-gpio, can sleep:
 gpio-100 (                    |led0                ) out lo

gpiochip1: GPIOs 504-511, parent: platform/soc:firmware:expgpio, raspberrypi-exp-gpio, can sleep:
 gpio-511 (                    |led1                ) in  hi

Above, the 'wakeup' and 'reset' names match the names listed in the modinfo wfx parameters description:

parm: gpio_reset:gpio number for reset. -1 for none. (int)
parm: gpio_wakeup:gpio number for wakeup. -1 for none. (int)
parm: power_mode:Force power save mode. 0: Disabled, 1: Allow doze, 2: Allow quiescent (int)
