Subject: gpio: mvebu_gpio: Add .request and .rfree methods for Armada 38x
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=7d8bb89d569b18899011c44f8129a6b95a1424a6;p=u-boot.git

gpio: mvebu_gpio: Add .request and .rfree methods for Armada 38x

To use particular pin GPIO, it needs to be first switched to GPIO by
pinctrl. Use pinctrl_gpio_request() and pinctrl_gpio_free() for this
purpose.
