Subject: [U-Boot] [PATCH v4 07/25] power: Export register access functions from as3722
Date: Mon, 30 Mar 2015 18:04:20 -0600	[thread overview]
Message-ID: <1427760278-4573-8-git-send-email-sjg@chromium.org> (raw)
In-Reply-To: <1427760278-4573-1-git-send-email-sjg@chromium.org>

With the full PMIC framework we may be able to avoid this. But for now
we need access to the PMIC.
