[PATCH v5 2/3] gpio: wm831x: Add basic device tree support

From: Charles Keepax
Date: Fri Mar 17 2017 - 06:41:49 EST


Now the wm831x-core has basic DT support we can update this driver to
allow use of the GPIOs within a device tree system.

No changes since v4, still should go through Lee's tree.

Thanks,
Charles
