[PATCH v4 0/2] Add compatibility for scmi clock protocol version 3.0

[Kamlesh Gurudasani]

Clock version 3.0 specified in ARM SCMI Platform design document
v3.2, adds extended_config_val parameter in CLOCK_CONFIG_SET.

The SCMI server with clock version 3.0 rejects the message if
it doesn't have this field.

Add support so that both SCMI server with clock version 2.0 and 3.0
can be handled.

While at it, fix the set_parent support for non CCF flow.
