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 thus 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 regression. Additionally some other patches are here suggested by Vladimir: - ensure MDIO children are scanned on post-bind is needed - sanity check DSA driver required ops are present - allow DSA drivers to not require xmit/recv functions - remove unecessary xmit/recv functions from ksz9477 driver v3: - fix mdios node in dt - add Vladimir's rb tag's v2: - added Ramon's rb tag's to first two patches - add patches for dsa-uclass to sanity check ops and make xmit/recv optional - fec: fix fallback for non conforming DM_MDIO dts - mv88e61xx: - rebase on v2022.07-rc2 (use ofnode_get_phy_node) - remove unused commented out fields from struct - remove unused PORT_MASK macro - remove phy from priv struct name - refactor code from original drivers/net/phy/mv88e61xx with suggestions from review to consolidate some functions into mv88e61xx_dsa_port_enable - remove unecessary skiping of disabling of CPU port - remove unecessary dev_set_parent_priv - remove unnecessary static init flag - replace debug with a dev_warn if switch device-id unsupported - remove unnecessary xmit/recv functions as we rely on the fact that only a single port is active instead of mangling packets Tested on a Gateworks GW5904 which has a Marvell 88E6176 switch hanging off the IMX6 FEC.
