Merge branch 'Fix-88x3310-leaving-power-save-mode'
Russell King says: ==================== Fix 88x3310 leaving power save mode This series fixes a problem with the 88x3310 PHY on Macchiatobin coming out of powersave mode noticed by Matteo Croce. It seems that certain PHY firmwares do not properly exit powersave mode, resulting in a fibre link not coming up. The solution appears to be to soft-reset the PHY after clearing the powersave bit. We add support for reporting the PHY firmware version to the kernel log, and use it to trigger this new behaviour if we have v0.3.x.x or more recent firmware on the PHY. This, however, is a guess as the firmware revision documentation does not mention this issue, and we know that v0.2.1.0 works without this fix but v0.3.3.0 and later does not. ==================== Signed-off-by: David S.
