Subject: [PATCH 12/16] i.MX: vf610: Add low-level pin configuration helper
Date: Mon,  5 Dec 2016 06:54:40 -0800	[thread overview]
Message-ID: <1480949684-18520-13-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1480949684-18520-1-git-send-email-andrew.smirnov@gmail.com>

Add low-level pin configuration helper for early boot code, and convert
pinctrl driver to use that code as well.
