This is another switch from Vitesse / Microsemi / Microchip, that has 10 ports (8 external, 2 internal) and is integrated into the Freescale / NXP T1040 PowerPC SoC. It is very similar to Felix from NXP LS1028A, except that this is a platform device and Felix is a PCI device, and it doesn't support IEEE 1588 and TSN. Like Felix, this driver configures its own PCS on the internal MDIO bus using a phy_device abstraction for it (yes, it will be refactored to use a raw mdio_device, like other phylink drivers do, but let's keep it like that for now). But unlike Felix, the MDIO bus and the PCS are not from the same vendor. The PCS is the same QorIQ/Layerscape PCS as found in Felix/ENETC/DPAA*, but the internal MDIO bus that is used to access it is actually an instantiation of drivers/net/phy/mdio-mscc-miim.c. But it would be difficult to reuse that driver (it doesn't even use regmap, and it's less than 200 lines of code), so we hand-roll here some internal MDIO bus accessors within seville_vsc9953.c, which serves the purpose of driving the PCS absolutely fine. Also, same as Felix, the PCS doesn't support dynamic reconfiguration of SerDes protocol, so we need to do pre-validation of PHY mode from device tree and not let phylink change it.
