Hi,

This serie is a preparation to shift the cpufreq of pxa2xx platforms to clocks
API.

The first 3 patches are review and merge material :
 - patch 1/4 for Viresh and Rafael
 - patches 2/4 and 3/4 for me

The 4th on is for review but not merge, as the clock changes must be fully
reviewed and go in first as a prequisite
Have you tested whether this patch set results in functional cpufreq
support - looking at drivers/clk/pxa, the CPU clock is read-only -
it can't be used to change the clock rate.  So, I very much doubt this
has been functionally tested.
Oh yes I did, on lubbock and mainstone ... but this requires another patchset
under review, here :

Don't forget that changing the CPU clock rate needs other changes
(like the memory clock rate) so all that code you're removing in
patch 4 (which does the actual clock change) needs to go somewhere.
Sure, here :

I would have been wiser to quote these URLs instead of speaking of "clock
changes must be fully review and go in first as a prequisite".

Cheers.
