Hi Gregory,

I took the commit which is already in next, updated the compatible
string to "marvell,armada-370-gpio" and ammended the commit message
accordingly.

This one is intended to replace the one in next if/when the the change
to the compatible string from "marvell,armada-370-xp-gpio" to
"marvell,armada-370-gpio" is accepted. ("gpio: mvebu: change compatible
string for PWM support")

Ralph
