Well, if I'm expected to apply this, the above is a bit terse.

It looks like the patch makes the qoriq-cpufreq driver handle some new
hardware, but the changelog doesn't say much about that.

I'm guessing that the clockgen support added here makes it possible
for qoriq-cpufreq to handle this chip, is that correct?
