Subject: [PATCH 4/9] mfd: da9063: add device specific init function
Date: Thu, 12 Apr 2018 09:22:26 +0200 [thread overview]
Message-ID: <20180412072231.31207-5-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20180412072231.31207-1-s.hauer@pengutronix.de>
From: Enrico Scholz <enrico.scholz@sigma-chemnitz.de>
Provide some more information about the used PMIC type; later patches
will add support for DA9062 which needs a custom init function.
