Subject: [PATCH 1/3 v2] net: introduce phylib
Date: Sun, 9 Sep 2012 17:44:00 +0200 [thread overview]
Message-ID: <1347205442-14299-1-git-send-email-plagnioj@jcrosoft.com> (raw)
Adapt phylib from linux
switch all the driver to it
This will allow to have
- phy drivers
- to only connect the phy at then opening of the device
- if the phy is not ready fail on open
Same behaviour as in linux and will allow to share code and simplify porting.
Signed-off-by: Jean-Christophe PLAGNIOL-VILLARD <plagnioj@jcrosoft.com>
---
v2:
update bus support
sync with linux 3.5
Best Regards,
J.
