I actually don't really agree with the reasoning here. We can perfectly
fine have several separate compatible strings, one for each SoC. We do
this for pinctrl, for clocks, and for many other drivers. Why should it
be different for the cpuidle driver? I know the function to enter idle
will most likely implemented in arch/arm/mach-mvebu/ because those
functions are generally too tightly coupled with a bunch of system
registers changes, but the description of the different idle states can
just as well be inside the cpuidle driver itself.
Thanks,
Thomas
