Thanks Florian,

The PSCI binding itself has provision for specifying function IDs for
different functions, and this seems to be followed by other subsystems
as well like SCMI:

Are you referring to this line in the devicetree linked?

+- arm,smc-id : SMC id required when using smc or hvc transports

I cannot find any prior definition of this in the devicetree yaml
format, so I will add that as well.
Did you have a link for the psci usage that you referenced?


Sure, line 80 and below from psci.yaml:

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree/bindings/arm/psci.yaml#n80
