From 83ad4305da1128111b2f063e41a740d1e19836c8 Mon Sep 17 00:00:00 2001
From: Jay at Control Module Industries <cmidroid@gmail.com>

Subject: [PATCH 7/7] cpsw: search for phy
I have encountered the same issue(s) on A6A boards.
I couldn't find a patch, so I wrote this patch to update the device tree
in the davinci_mdio driver in the 3.15.1 tree, it seems to correct it. I
would welcome any input on a different approach.
