Ticket #191 (closed enhancement: wontfix)
set CPU voltage to 1.8V on 200MHz or less

The S3C2410 data sheet only specifies that the 266MHz CPU type requires 2.0V (we
run it at 2.1V), and the 200MHz variant requires 1.8V.
However, if we dynamically change the CPU speed of the 266MHz variant down to
200 (or below), can we safely reconfigure the voltage to 1.8V? If yes, this
would give us even more power savings than just reducing the clock rate by cpufreq.
- Summary changed from investigate if we can set CPU voltage to 1.8V on 200MHz or less to set CPU voltage to 1.8V on 200MHz or less
