This patch introduces Microchip LAN966X ARMv7 based SoC family
of multiport gigabit AVB/TSN-capable ethernet switches.
It supports two SKUs: 4-port LAN9662 with multiprotocol
processing support and 8-port LAN9668 switch.

LAN966X includes copper and serial ethernet interfaces,
peripheral interfaces such as PCIe, USB, TWI, SPI, UART, QSPI,
SD/eMMC, Parallel Interface (PI) as well as synchronization
and trigger inputs/outputs.

v1 -> v2:
- Removed lan966x_dt_device_init().
  System boots fine without this function.

Your name fixed with your permission and as Rob suggested in a previous 
series.

Kconfig and Makefile files updated to avoid merge conflict with SAMA7G5 
that was integrated in 5.15-rc1.

This compatibility string will need to be documented in 
Documentation/arm/microchip.rst
and
Documentation/devicetree/bindings/arm/atmel-at91.yaml (or a similar 
file, as you wish).

You'll add it to your DT patches.

All the rest looks good to me: no need to resend. It's queued in 
at91-soc branch targeting 5.16.
You'll see it appearing in linux-next in the next few days.

Best regards,

Hello,

I wanted to reply earlier but I still have a few comments...

I don't think SOC_LAN966X is a good name or said differently as it is
not part specific, I don't get why this isn't merged with SOC_LAN966. I
would have one or the other.

I'm not sure all those include are actually used.

Yes and you'll have to document lan9662 and lan9668. Really, wildcards
in the compatible strings are usually not a good idea.

Well, I'm still wondering one thing, is arch/arm/mach-at91/lan966x.c
necessary at all to boot the platform?

I am using two different names to represent LAN966 as a new SoC family and 
LAN966X as its SKU's - LAN9662 and LAN9668
