[PATCH 00/14] SCMI multi-channel and optee shm

Dear all,

This series implements 2 features in driver/firmware/scmi.

First, a single change adds support for SCMI OP-TEE transport to
use OP-TEE native shared memory. See the 1st patch in this series:
"firmware: scmi: optee: use TEE shared memory for SCMI messages".

Then come changes for supporting multi-channel in the SCMI drivers.
I've split the implementation in 11 several small incremental changes
in the hope it helps the review. Few minor fixup commits are also
inserted in the series. 

Regards,
Etienne
