Subject: [PATCH 3/4] pinctrl: ocelot: Add support for Luton platforms
From: Lars Povlsen <lars.povlsen@...rochip.com>
This patch adds support for Luton pinctrl, using the ocelot driver as
basis. It adds pinconfig support as well, as supported by the
platform.
gclement: Split from a larger patch adding support all platforms in
the same time.
