kernel: mac80211: set the parent of the ath9k gpio_chip
This allows gpiolib to re-use ath9k's devicetree node as GPIO controller. Example: ath9k: ath9k@0 { #gpio-cells = <2>; gpio-controller; } Now the ath9k node can be used just like any other GPIO controller: gpios = <&ath9k 1 GPIO_ACTIVE_HIGH>; Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>
