Hi Arnd,

Here you're dropping pxa variant support. For the currently "partly" working
boards in devicetree, such a zylonite, this will break their current support.

For example the zylonite I have which is working on DT has a pxa310 variant.
The cm-x300, which also works in DT, has a pxa320 variant.

What these boards need is their IO mappings and cpufreq to still work after
your serie in DT. What bothers me are the changes to :
- drivers/clk/pxa/clk-pxa3xx.c
- drivers/cpufreq/pxa3xx-cpufreq.c

Here the clock changes will probably remove the clock provided to specific
pxa310/pxa320 drivers for example.

I don't know how you want to proceed, yet this change will break some pxa3xx
platforms.

Cheers.
