The current support is for the IP from Cadence.  There can be multiple SoC developed based on this IP and it is for
the SoC companies to build in support as and when the SoC support needs to be available.

Since the CIX SoC is available, it can be send together with this patch. 
However, I do not understand the need for  clubbing these in a single patch.
