I am not sure if this is documented, but SoC support (device tree, some
drivers, and config changes) usually go through the arm-soc tree curated
by Arnd, Olof and Kevin.

The MAINTAINERS entry for ARM64 port tries to call this out but it is
not obvious that architecture and platforms support is maintained
separately though in coordination.

Hope this helps.

Thanks,
Punit
