Subject: [PATCH] pinctrl: bcm2835: Direct GPIO config changes to
|
|
generic pinctrl
|
|
|
|
commit b6e5531c0f80de2779c87d0235b4fde5310a83b5 upstream.
|
|
|
|
In order to support GPIO config changes direct these to the generic pinctrl.
|
|
This also requires an adjust of the return code for unsupported parameter
|
|
otherwise gpiod_configure_flags wont work as expected.
