2018-01-03Merge branch 'mvneta-phylink'David S. Miller
Russell King says: ==================== Convert mvneta to phylink This series converts mvneta to use phylink, which is necessary to support the SFP cages on SolidRun's Clearfog platform. This series just converts mvneta without adding the DT parts - having discussed with Andrew, we believe we're too close to the merge window to submit that patch. I've split the "net: mvneta: convert to phylink" patch up to make it easier to review, and in doing so, spotted some minor corner cases that needed to be fixed along the way. This series depends on the previously merged phylink patches in netdev, along with the recently reviewed 7 patch series "Resolve races in phy accessors" without which, the race described in patch 5 of that series is very evident when triggering a dummy hibernate cycle. This series also illustrates how to convert mvpp2 to phylink. mvneta is the only user of the fixed_phy_update_state() API, and this becomes redundant with the conversion. It would be good to get this series not only reviewed, but also independently tested to ensure that I haven't missed anything - I only have the Clearfog platform to test on, and that doesn't support all the different interface modes that mvneta supports. A particularly interesting side effect of this series is that DSA switches no longer need the "CPU" port and DSA facing MAC ethernet instance to be marked as a fixed link anymore with mvneta - we can use 1000BaseX mode, and the DSA to CPU link will use the 802.3z negotiation to determine the link properties without needing the link parameters to be explicitly stated in DT - that is a subject of a future patch. ==================== Signed-off-by: David S.

The PSC sync change interrupt can fire multiple times while the link is down, which is caused by noise on the serdes lines.

2018-01-03net: mvneta: ensure PM paths take the rtnl lockRussell King
The netdev core always ensures that the rtnl lock is held while calling the ndo_open() and ndo_stop() methods. However, the suspend/resume paths do not hold the rtnl lock. phylink will expect the rtnl lock to be held when the MAC driver calls it, so we end up with kernel warnings. Take the lock to ensure that these functions are called in a consistent manner. Signed-off-by: Russell King <rmk+kernel@armlinux.org.uk> Signed-off-by: David S. Miller <davem@davemloft.net>
