 don't know yet, but the PMIC does 3A @ 1V (!!) for the CPU and the
same amount for the GPU (!).

 it'll almost certainly have to be down-clocked to 1ghz, or a special
cpufreq arrangement to be made where 2 cores are allowed to run up to
the maximum 1.8ghz and the other two are capped at say 400mhz or less,
something like that.

 it's a 4-core 28nm where the A20 was a 2-core 40nm, so that's a 1/2
power-saving factor... running at 1ghz should be a roughly equal power
consumption.... but the RK3288 is an A17, the A20 is an A7.

 just have to see how it goes, basically.
