We are using multiple scmi instances within a VM and hypervisor associates a tag with each instance and expects the tag in smc calls from that instance, while sharing the same smc-id(func_id) among the instances. This patch series introduces new optional dtb bindings which can be used to pass parameters to smc/hvc calls.
