[PATCH v2 0/2] Allow parameter in smc/hvc calls

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 hvc 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.
