Subject: [PATCH 6/6] ARM: i.MX6 Phytec PFLA02: Add supplies for the SoC internal regulators
Date: Wed, 30 Sep 2015 16:05:46 +0200 [thread overview]
Message-ID: <1443621946-8712-7-git-send-email-s.hauer@pengutronix.de> (raw)
In-Reply-To: <1443621946-8712-1-git-send-email-s.hauer@pengutronix.de>
The SoC internal regulators for the CPU and the SoC come from the
DA9063 vdd_core and vdd_soc. Add this relationship to the device tree
so that the voltage drop on the SoC internal LDO regulators can be
minimized.
