From a5597008dbc230876db2d344561d634f4d52ea4a Mon Sep 17 00:00:00 2001 From: Andrew Lunn Date: Mon, 31 Aug 2015 15:56:53 +0200 Subject: 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.
