How old or new are these SoCs ? The reason I ask is that it is really
sad to see vendors still creating their custom interfaces for such things
despite the standard SMCCC interface SOC_ID introduced in SMCCC v1.2 some
time in 2020.

Hopefully they migrated to the std interface and just use the driver in
the kernel without needing to add this every time they fancy playing
with the interface for no reason.
