Merge branch 'cpsw'
Mugunthan V N says: ==================== Add DRA7xx and AM43xx platform support in cpsw-phy-sel driver Adding DRA7xx and AM43xx platform support to cpsw-phy-sel driver to select phy mode in control driver and fixing the uninitialized dev by initializing to platform device structure pointer. Changes from Initial version * Added back the missing patch (1/3) ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
