From 3104a6ff67e484e4dc84822b4ed0396e85bb9fb9 Mon Sep 17 00:00:00 2001 From: Anton Vorontsov Date: Thu, 16 Jul 2009 21:31:47 +0000 Subject: [PATCH] ucc_geth: Revive fixed link support Since commit 0b9da337dca972e7a4144e298ec3adb8f244d4a4 ("Rework ucc_geth driver to use of_mdio infrastructure") the fixed-link support is broken. This patch fixes the support by removing !ug_info->phy_node check, and adds a call to of_phy_connect_fixed_link() if a phy is not attached to the MAC. Also, remove an old fixed-link code that we don't use any longer. Signed-off-by: Anton Vorontsov Signed-off-by: Grant Likely Signed-off-by: David S.
