The as370.dtsi for Synaptics AS370 SoC does not have a user (DTS board
file), is uncompilable and untestable.  It was added back in 2018.  No
user appeared since that time, so assume it won't be added.

I assume Arnd/Olof will take this.

Sure, I can take that, but it would be nice to hear anything from Jisheng Zhang
about this.

I can see that the only two 64-bit Synaptics SoCs are as370 and bg4ct,
but both of them have apparently been replaced with newer versions that
never made it into the kernel: as371, as390, bg5ct, according to press
releases.

Jisheng, can you clarify whether you plan to complete the as370 support
or add the later SoCs?

Hi Arnd, Rob, Krzysztof

Sorry for being late. I was on vocation in the past several days.
As for this as370 removing, I think we'd better keep it. I planned
to submit the as370-rdk board dts two years ago, but latter I focused
on Synaptics SoCs related drivers support such as gpio, pcie, sdhci and
so on. I will send a basic as370 rdk board dts. I'm also considering
to mainline basic support for a new SoC.

Ok, sounds good. Let's keep it for now then. If you have the dts file at
hand, please send the patch to soc@kernel.org directly so I can still
apply it for 5.15 to enable it for build testing, even if it's still missing
functionality.
