Subject: [PATCH v1] pinctrl: baytrail: Re-use data structures from pinctrl-intel.h (part 2)
Date: Fri, 26 Jul 2019 23:16:36 +0300	[thread overview]
Message-ID: <20190726201636.53129-1-andriy.shevchenko@linux.intel.com> (raw)

We have some data structures duplicated across the drivers.
Let's deduplicate them by using ones that being provided by
pinctrl-intel.h.
