Subject: [PATCH net-next 0/3] net: dsa: mxl-gsw1xx: setup polarities and
 validate chip

Now that common PHY properties make it easy to configure the SerDes RX and TX
polarities, use that for the SGMII/1000Base-X/2500Base-X PCS of the MaxLinear
GSW1xx switches.

Also, validate hardware in probe() function to make sure the switch is
actually present and MDIO communication works properly.
