Thanks for explanation. As fair as I understand, Bartlomiej wanted to
merge this in a way which would avoid loosing the boost mode. Kukjin
prepared topic branches for previous cpu-freq/clk stuff so maybe
everything could go through PM?
We aren't loosing anything at all. There can be two cases here:

1. Patch 1/6 and 6/6 make it to 4.3 (with suggested changes) via PM tree:
- All will work fine in this case, no issues at all..

2. They don't make it:
- Even in this case, nothing will break. Users can just enable a
  config option and that's all..
Users don't need to enable the config option to get boost
functionality working.  It is only needed to get scaling_boost_freqs
sysfs attribute visible (which lists available boost freqs) when
using cpufreq-dt driver.  Also the config option in question is not
user visible.

The worst thing that happens if these 2 PM patches don't make it
in time is that there will be no scaling_boost_freqs available
when using cpufreq-dt driver.  Which is not very important from
Exynos4x12 POV as it only supports single boost freq currently.
So, no need to divert things into another tree this late.
I agree.
Over that, Rafael will not be around for 2 weeks now (Plumbers and
other stuff) ..

So, just target the cpufreq core changes via PM tree.. rest is just
fine.

I hope that makes sense :)
Yes. :)
