[RFC PATCH 4/4] ARM: dts: imx6qdl: Add PU power-domain information to gpc node

From: p.zabel@pengutronix.de (Philipp Zabel)
Date: 2014-02-11 13:27:11
Also in: linux-devicetree
Subsystem: the rest · Maintainer: Linus Torvalds

Possibly related (same subject, not in this thread)

The PGC that is part of GPC controls isolation and power sequencing of the
PU power domain. The power domain will be handled by the generic pm domain
framework and needs a phandle to the PU regulator to turn off power when
the domain is disabled.
