Merge branch 'dsa-gpio-reset'
Andrew Lunn says:
====================
DSA: GPIO to reset switches
These two patches add support for using a GPIO to hard reset a switch
during reset.
v2:
Thanks to a clue from Neil Armstrong, i figured out how to convert the
gpio into a gpiod, while keeping the ACTIVE_LOW flag, so simplifiying
the set/reset code.
I have not included the Tested-by: from Phil Reid, since i made a lot
of changes.
