Subject: [PATCH] omap: i2c: Add calls for pinctrl state select
Date: Fri, 17 Apr 2015 17:07:57 +0200	[thread overview]
Message-ID: <1429283277-28161-1-git-send-email-pascal.huerst@gmail.com> (raw)

From: Pascal Huerst <pascal.huerst-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

This adds calls to pinctrl subsystem in order to switch pin states
on suspend/resume if you provide a "sleep" state in DT.
