The clock to the ARM TWD local timer scales with the cpu
frequency. To allow the cpu frequency to change while
maintaining a constant TWD frequency, pick a lower target
frequency for the TWD and use the prescaler to divide down
to the closest lower frequency.
We are using this with some custom hooks for the U8500.

Martin Persson can probably provide an additional Tested-by
from ST-Ericsson if it helps.

Colin are you merging this patch for 2.6.39 through
Russells tracker or pull request? It's an important patch
for us.

Yours,
Linus Walleij
