the first one is in deprecation process, it probably not

Mauro Carvalho Chehab d888f8d7d8 [media] doc-rst: Fix license for the media books
The kAPI, v4l-drivers and dvb-drivers never used the
GNU FDL license. The addition of such license header were
just due to copy-and-paste. So, let's fix it.

As the media_kapi were part of device-drivers.tmp, it is
under GPL v2+.

The other two books is an agregation of files without any
license explicitly specified. So, they're all bound to the
Kernel's COPYING license. So, they're GPL v2 only.

The uAPI book has 5 parts, but they lost numeration after

the annexes.

At each part, use :maxwidth: 5, in order to show a more

Andreas Herrmann da7d3abe1c Revert "cpufreq: pcc-cpufreq: update default value of cpuinfo_transition_latency"
This reverts commit 790d849bf8.

Using a v4.7-rc7 kernel on a HP ProLiant triggered following messages

 pcc-cpufreq: (v1.10.00) driver loaded with frequency limits: 1200 MHz, 2800 MHz
 cpufreq: ondemand governor failed, too long transition latency of HW, fallback to performance governor

The last line was shown for each CPU in the system.
Testing v4.5 (where commit 790d849b was integrated) triggered
similar messages. Same behaviour on a 2nd HP Proliant system.

So commit 790d849bf (cpufreq: pcc-cpufreq: update default value of
cpuinfo_transition_latency) causes the system to use performance
governor which, I guess, was not the intention of the patch.

Enabling debug output in pcc-cpufreq provides following verbose output:

 pcc-cpufreq: (v1.10.00) driver loaded with frequency limits: 1200 MHz, 2800 MHz
 pcc_get_offset: for CPU 0: pcc_cpu_data input_offset: 0x44, pcc_cpu_data output_offset: 0x48
 init: policy->max is 2800000, policy->min is 1200000
 get: get_freq for CPU 0
 get: SUCCESS: (virtual) output_offset for cpu 0 is 0xffffc9000d7c0048, contains a value of: 0xff06. Speed is: 168000 MHz
 cpufreq: ondemand governor failed, too long transition latency of HW, fallback to performance governor
 target: CPU 0 should go to target freq: 2800000 (virtual) input_offset is 0xffffc9000d7c0044
 target: was SUCCESSFUL for cpu 0

I am asking to revert 790d849bf to re-enable usage of ondemand
governor with pcc-cpufreq.

Daniel Vetter 47d6d752b9 doc/sphinx: Enable keep_warnings
Unfortunately warnings generated after parsing in sphinx can end up
with entirely bogus files and line numbers as sources. Strangely for
outright errors this is not a problem. Trying to convert warnings to
errors also doesn't fix it.

The only way to get useful output out of sphinx to be able to root
cause the error seems to be enabling keep_warnings, which inserts
a System Message into the actual output. Not pretty at all, but I
don't really want to fix up core rst/sphinx code, and this gets the job
done meanwhile.

Sphinx is really evil when an older version finds an extra
attribute for the :toctree: tag: it simply ignores everything
and produce documents without any chapter inside!

As we're now using tags available only on Sphinx 1.4.x, we
need to use some creative ways to add a title before the

There were several files under Documentation/video4linux/bttv.

Instead of simply copying them to the rst folder, I opted to
merge into a single document and adjust the headers to
adjust the section levels and fix the cards tables.

There are two exceptions on the merge:

- The Tuners were renamed as a separate document, as they
  describe a separate driver;

- I removed the PROBLEMS section. It describes problems with
  the very first generation of 3D boards (Mistique/S3).
  It sounds very unlikely that someone would still need to
  install a bttv board on such hardware. Also, it is not
  very well written, IMHO.
