Signed-off-by: Ralph Sennhauser --- Hi everyone, this patch uses "marvell,armada-370-gpio" for the compatible property and as such depends on the rename of the property to still make it in in time for 4.12 ("gpio: mvebu: change compatible string for PWM support"). Otherwise the compatible string will need to be amended to "marvell,armada-370-xp-gpio". Checked the functional spec and the register ranges and offsets are the same as for armada-xp. Likely the same holds true for the armada-39x family, though I neither have access to the spec nor any such hardware.
