[PATCH 2/4] ARM: kirkwood: add device node entries for the gigabit interfaces

Florian Fainelli florian at openwrt.org
Fri Mar 29 14:14:37 EDT 2013


This patch modifies kirkwood.dtsi to specify the various gigabit
interfaces nodes available on kirkwood devices. They are disabled by
default and should be enabled on a per-board basis. egiga0 and egiga1
aliases are defined for convenience. The mdio node is also present and
should be enabled on a per-board basis as well.
