From 64d76608598b40801b384a87a5ba5aec2772c3de Mon Sep 17 00:00:00 2001 From: Hauke Mehrtens Date: Fri, 20 Dec 2013 02:16:11 +0100 Subject: [PATCH] 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.
