Subject: [PATCH 1/2] pinctrl: pinctrl-single must be initialized early.
Date: Thu, 20 Sep 2012 09:34:48 +0300	[thread overview]
Message-ID: <1348122889-28271-2-git-send-email-panto@antoniou-consulting.com> (raw)
In-Reply-To: <1348122889-28271-1-git-send-email-panto@antoniou-consulting.com>

When using pinctrl-single to handle i2c initialization, it has
to be done early.
On the beaglebone the regulator is connected to the i2c0 bus,
and for sure that's the case for many other am33xx boards.
