From b0ac9564061265dd14e6f8f777622e3401b82b4b Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Thu, 5 Dec 2013 14:52:15 -0800 Subject: [PATCH] arc_emac: remove custom "max-speed" parsing code The ARC emac driver was the only in-tree to parse a PHY device 'max-speed' property but yet failed to do it correctly because 'max-speed' is supposed to set a PHY device supported features, not the advertising features as it was done. Now that of_mdiobus_register() takes care of doing that, remove the custom 'max-speed' parsing code. Signed-off-by: Florian Fainelli Signed-off-by: David S.
