[PATCH net-next v3 1/8] dt-bindings: net: realtek,rtl9301-mdio: Add RTL83xx series

[Markus Stockhausen <markus.stockhausen@gmx.de>]

The lower end Realtek Otto switches provide 1G only and are divided into
two series:

- Maple  : RTL838x up to 28 ports
- Cypress: RTL839x up to 56 ports

The Maple based devices have 3 different SoCs: RTL8380, RTL8381 and
RTL8382. The Cypress series consists of the RTL8391, RTL8392 and
RTL8393 SoCs. The MDIO controller of these switches works like the
existing RTL93xx logic but has different characteristics and different
registers. Add new compatibles in the device tree.

With the extended compatibility list change the title to better reflect
the scope of. Especially add the "Ethernet" tag as these devices have
multiple MDIO controllers.
