Subject: [PATCH v2 02/10] davinci: add mdio platform devices
Date: Thu, 2 Sep 2010 18:03:20 -0400 [thread overview]
Message-ID: <1283465008-18606-3-git-send-email-cyril@ti.com> (raw)
In-Reply-To: <1283465008-18606-1-git-send-email-cyril@ti.com>
This patch adds mdio platform devices on SoCs that have the necessary
hardware. Clock lookup entries (aliases) have also been added, so that the
MDIO and EMAC drivers can independently enable/disable a shared underlying
clock. Further, the EMAC MMR region has been split down into separate MDIO
and EMAC regions.
