Subject: [PATCH 5/6] regulator: i.MX anatop: Allow supply regulator
Date: Wed, 30 Sep 2015 16:05:45 +0200 [thread overview]
Message-ID: <1443621946-8712-6-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1443621946-8712-1-git-send-email-s.hauer@pengutronix.de>
The anatop regulators are SoC internal LDO regulators usually supplied
by an external PMIC. This patch adds support for specifying the supply
from the device tree using the vin-supply property.
