v7:
- Rebase to latest wireless-drivers-next.
v6:
- Convert line comments to block comments.
v5:
- Fix a dt_binding_check error by including
<dt-bindings/gpio/gpio.h> in microchip,wilc1000.yaml.
v4:
- Simplify wilc_wlan_power() by letting gpiod_set_value()
handle NULL gpios.
v3:
- Fix to include correct header file.
- Rename wilc_set_enable() to wilc_wlan_power().
- Use devm_gpiod_get{,_optional}() instead of of_get_named_gpio()
- Parse GPIO pins once at probe time.
v2:
- Split documentation update and driver changes into seprate
patches.

wilc1000: Add reset/enable GPIO support to SPI driver
wilc1000: Document enable-gpios and reset-gpios properties
