[PATCH net-next 00/24] net: dsa: MT7530, MT7531, and MT7988 improvements

[arinc9.unal at gmail.com]

Hello!

This patch series is focused on simplifying the code, and improving the
logic of the support for MT7530, MT7531, and MT7988 SoC switches.

There're two fixes. One for fixing the corrupt frames using trgmii on MCM
MT7530 with 40 MHz oscillator on certain MT7621 SoCs. The other for fixing
the port capabilities of the switch on the MT7988 SoC.

Currently, using multiple ports as CPU ports won't work properly. I am
working on fixing it.

I am leaving this information for the record, as I have not received any
comments on my RFC series regarding this. The register may need to be
protected from being accessed by processes while the operation that
modifies the MT7530_MHWTRAP register on mt7530_setup_port6() is being done.
I don't see this being done on mt7530_setup() but it's there on
mt7530_setup_port5(). My tests haven't shown any apparent issues but if you
experience any issues with port 6, this is where to look first.

I have done iperf3 and ping tests on all ports of the MT7530 switch with
this patch series applied. I tested every possible configuration on the MCM
and standalone MT7530 switch. I'll let the name of the dtb files speak for
themselves.
