Subject: gpio: axp/sunxi: Remove virtual VBUS detection GPIO
X-Git-Url: http://git.dujemihanovic.xyz/img/static/git-favicon.png?a=commitdiff_plain;h=09cbd3858f156e0461c0c939f23cf3c76ef95dcc;p=u-boot.git

gpio: axp/sunxi: Remove virtual VBUS detection GPIO

Now that this functionality is modeled using the device tree and
regulator uclass, the named GPIO is not referenced anywhere. Remove it.
