Subject: [PATCH v4 net-next 10/11] net: dsa: felix: introduce support for Seville VSC9953 switch

From: Maxim Kochetkov <fido_max@...ox.ru>

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.

Changes in v4:
Split devicetree documentation in separate patch.
Removed 2500base-x from phylink validation since it isn't actually
supported.

Changes in v3:
Register this driver from felix.c.
Make the driver name for seville "mscc_seville" and for felix
"mscc_felix" instead of KBUILD_MODNAME ("mscc_felix") for both.
Rebased on top of the felix "phylink_mac_link_up" conversion, the PCS
ops that Seville is calling are now different.

Changes in v2:
Now supporting Seville as part of the Felix driver. This has several
advantages: a lot more code reuse (not only from felix.c, but also from
the low-level felix_vsc9959.c, the PCS initialization being an example).
But also a disadvantage: the common driver depends on PCI, but Seville
is not a PCI device.
Added devicetree bindings documentation.
