Add a basic support for AS370-RDK board based on the AS370 SoC. We can
get a basic shell on the uart console now.

Hi Arnd,
If it's too late, I will add it in a PR for 5.16 in next development window.
Thanks

There is no such binding. You need to update the bindings file (first
patch in the series).

This is my plan ;) In fact, "berlin4ct" related binding is also missing.
I want to convert Documentation/devicetree/bindings/arm/syna.txt
to yaml, then add missing bindings. But it's too late for 5.15,
If it's fine to keep as370.dtsi without board user(s), we can drop
this patch. I will solve this issue in next development window.
Thanks

Yes, doing it for the next cycle is ok.

Hi Arnd and Jisheng,
This patch was discussed in Aug 2021 and since then there was no resend.
I assume that AD370 will not get a board, so I propose to pick up my
removal patch:
https://lore.kernel.org/all/[email protected]/
I will resend it.
Best regards,
Krzysztof
