The "cpus" clock is the clock for the embedded processor in the A80. It is also part of the PRCM clock tree. This clock includes a pre- divider on one of its inputs. For now we are using a custom clock driver for it. In the future we may want to develop a generalized driver for these types of clocks, which also includes the AHB clock driver on sun[5678]i.

I have no idea what you are talking about :)

Same thing here, if it's only used in the A80, just compile it when ARCH_SUN9I is compiled.
