[RFC 0/3] CPU frequency scaling for GTA02

[Rask Ingemann Lambertsen]

   Hi.

   This patch set adds support for cpu frequency scaling on the GTA02. It is
definitely WIP, because at the moment all that works is this:

# echo >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor powersave
(switches to 100 MHz core frequency and 1.1 V core power supply)

# echo >/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor performance
(switches to 400 MHz core frequency and 1.5 V core power supply)

Switching to the 'ondemand' or 'conservative' governors simply doesn't work
and I don't know why.

Handling clocks like those found in the S3C2442B is way beyond the
capabilities of the Linux clock support at present. That's why only 100 MHz
and 400 MHz is available.
