Nit pick ... any reason why we append 'cluster' here? The TRM just says
the "CPU Complex" consists of two CPU clusters. So
"nvidia,tegra186-cpu-complex" or "nvidia,tegra186-ccplex" seems fine.
BTW, I do see references in the TRM to CCPLEX_CLUSTER0/1, but never
CCPLEX_CLUSTER in reference to both. I think it is just CCPLEX AFAICT.
The reason was that the MMIO aperture is called "CCPLEX_CLUSTER" in the
address map. But I agree it's not a very descriptive name.
Cheers
Jon
