Message-Id: <1387502173-21743-7-git-send-email-hauke@hauke-m.de> Date: Fri, 20 Dec 2013 02:16:11 +0100 From: Hauke Mehrtens <hauke@...ke-m.de> To: davem@...emloft.net Cc: zambrano@...adcom.com, netdev@...r.kernel.org, f.fainelli@...il.com, Hauke Mehrtens <hauke@...ke-m.de> Subject: [PATCH v3 6/8] 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.
