  Currently, smc/hvc calls are made with parameters set
to zeros. 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.

  dt-bindings: firmware: arm,scmi: support parameter passing in smc/hvc
  firmware: arm_scmi: Augment SMC/HVC to allow optional parameters
