X-Git-Tag: omap-for-v4.3/fixes-rc1~110^2~21^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a5597008dbc2;p=pandora-kernel.git phy: fixed_phy: Add gpio to determine link up/down. An SFP module may have a link up/down status pin which can be connection to a GPIO line of the host. Add support for reading such an GPIO in the fixed_phy driver.
