[PATCH 0/6] Add MV88E61xx DSA driver and use on gwventana

This series adds a DSA driver for the MV88E61xx based on
drivers/net/phy/mv88e61xx and uses in on the gwventana_gw5904_defconfig.

The hope is that the other three boards that use the MV88E61xx driver
can move to this as well eventually so that we can remove the non-dm
driver and the 4 Kconfig options it requires.

The MV88E61xx has an MDIO interface this DM_MDIO must be used so support
for a UCLASS_MDIO driver is added to the fec_mxc ethernet driver in a
way that allows a fallback to the previous non DM_MDIO case as there are
many boards out there using this driver that define DM_MDIO but do not
have the required dt props for a DM_MDIO driver which would cause a

Additionally a patch to ensure MDIO children are scanned on post-bind is

I'm making use of the dm_mdio_read/dm_mdio_write wrapper from Merak that
is pending so it is in this series as well.

Best Regards,
