From bea69c47f5b93b3142f8833f8a34b666d5d7d6a7 Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Fri, 20 Dec 2013 02:16:11 +0100 Subject: b44: activate PHY when MAC is off Without this patch we can not access the PHY when the MAC is switched off. This PHY access is needed to configure the switch, which is done through PHY registers. Signed-off-by: Hauke Mehrtens Signed-off-by: David S.
