Subject: [PATCHv3 6/6] ARM: sunxi: Add EMAC Controller to Hackberry dt
Date: Fri, 24 May 2013 11:23:14 +0200	[thread overview]
Message-ID: <1369387394-9453-7-git-send-email-maxime.ripard@free-electrons.com> (raw)
In-Reply-To: <1369387394-9453-1-git-send-email-maxime.ripard@free-electrons.com>

The Hackberry has a PHY that needs to be powered up through a GPIO, so
we need to use a fixed regulator here.
