From d22960c8bbb8f685c2d8c4051e1f335ab13dca24 Mon Sep 17 00:00:00 2001 From: Cyril Chemparathy Date: Wed, 15 Sep 2010 10:11:22 -0400 Subject: davinci: add mdio platform devices 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. Signed-off-by: Cyril Chemparathy Acked-by: David S.
