Currently, smc/hvc calls are made with parameters set
to zeros. We are using multiple scmi instances within
a VM. We are sharing the same smc-id(func_id) with all
scmi instance. The hypervisor needs a way to distinguish
among hvc calls made from different instances.

This patch series introduces new compatible string which
can be used to pass shmem channel address as parameters
to smc/hvc calls.

Applied to sudeep.holla/linux (for-next/scmi/updates), thanks!
Hi Sudeep, our hypervisor team is evaluating other scmi transport
options(including new qcom specific transport) along with this one so there
is a possibility that we might not use this solution. If you think this
patch is not useful to others, you can hold off its merge. Sorry about the
last minute inconvenience.
Firstly, not sure why you took this in private. I am going to reply on the
list and from now on I will never trust or rush to take any Qualcomm changes.
Nothing personal but I have to follow that to keep it simple. It is in
Linux tree yesterday or today and yes it is too late.
I understand your frustration and trust me I am even more disappointed by the decision by our hypervisor team and that too this late.  My efforts on this series are all wasted. If you like me to post a revert of this patch series, I will be happy to do that. Please don't let this one example reflect whole Qualcomm culture. Again, extremely sorry about all the efforts you put in.
