Hi Jason, On lun., ao?t 15 2016, Jason Cooper [off-list ref] wrote:
By assigning the pin hog to the pinctrl node, we correctly configure the MPPs. However, they are not available to userspace. Fix this by assigning the hogs to the gpio node. After this, the following works as expected: # echo 28 >/sys/class/gpio/export # echo low >/sys/class/gpio/gpio28/direction Signed-off-by: Jason Cooper <redacted>
Applied on mvebu/dt with Reviewed-by flag from Andrew and I changed the title to "ARM: dts: kirkwood: ..." Thanks, Gregory
