This adds support for the EDPD PHY tunable. Per default EDPD is disabled in interrupt mode, the tunable can be used to override this, e.g. if the link partner doesn't use EDPD. The interval to check for energy can be chosen between 1000ms and 2000ms. Note that this value consists of the 1000ms phylib interval for state machine runs plus the time to wait for energy being detected. v2: - consider that phylib core holds phydev->lock when calling the phy tunable hooks Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Simon Horman <simon.horman@corigine.com> Signed-off-by: David S.
