Alvin Šipraga 4af2950c50 net: dsa: realtek-smi: add rtl8365mb subdriver for RTL8365MB-VC
This patch adds a realtek-smi subdriver for the RTL8365MB-VC 4+1 port
10/100/1000M switch controller. The driver has been developed based on a
GPL-licensed OS-agnostic Realtek vendor driver known as rtl8367c found
in the OpenWrt source tree.

Despite the name, the RTL8365MB-VC has an entirely different register
layout to the already-supported RTL8366RB ASIC. Notwithstanding this,
the structure of the rtl8365mb subdriver is loosely based on the rtl8366rb
subdriver. Like the 'rb, it establishes its own irqchip to handle
cascaded PHY link status interrupts.

The RTL8365MB-VC switch is capable of offloading a large number of
features from the software, but this patch introduces only the most
basic DSA driver functionality. The ports always function as standalone
ports, with bridging handled in software.

One more thing. Realtek's nomenclature for switches makes it hard to
know exactly what other ASICs might be supported by this driver. The
vendor driver goes by the name rtl8367c, but as far as I can tell, no
chip actually exists under this name. As such, the subdriver is named
rtl8365mb to emphasize the potentially limited support. But it is clear
from the vendor sources that a number of other more advanced switches
share a similar register layout, and further support should not be too
hard to add given access to the relevant hardware. With this in mind,
the subdriver has been written with as few assumptions about the
particular chip as is reasonable. But the RTL8365MB-VC is the only
hardware I have available, so some further work is surely needed.
