Subject: of/mdio: Add support function for Ethernet fixed-link property
X-Git-Tag: v2.6.31-rc5~83^2~24
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=24c30dbbcdda9aeccb23b4eecb6bb8e538742ea4;p=pandora-kernel.git

of/mdio: Add support function for Ethernet fixed-link property

Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet
device drivers.  The "OF MDIO rework" patches removed most of the
support. Instead of re-adding fixed-link stuff to the drivers, this
patch adds a support function for parsing the fixed-link property
and obtaining a dummy phy to match.

Note: the dummy phy handling in arch/powerpc is a bit of a hack and
needs to be reworked.  This function is being added now to solve the
regression in the Ethernet drivers, but it should be considered a
temporary measure until the fixed link handling can be reworked.
