This patch set introduces support for an internal MDIO bus in LAN937x
switches, enabling the use of a side MDIO channel for PHY management
while keeping SPI as the main interface for switch configuration.

changes v3:
- add "net: dsa: microchip: parse PHY config from device tree" patch

other changelogs are added to separate patches.
