It's totally outdated.  We need a revised version later, maybe better
integrated into kernel doc.

Modern machines tend to have only one headset jack nowadays, and they
often need these quirks.  Let's allow them applicable via model
option for ease of debugging.

ASoC: Updates for v4.1

More updates for v4.1, pretty much all drivers:

 - Lots of cleanups from Lars, mainly moving things from the CODEC level
   to the card level.
 - Continuing improvements to rcar from Morimoto-san, pcm512x from
   Howard and Peter, the Intel platforms from Vinod, Jie, Jin and Han,
   and to rt5670 from Bard.
 - Support for some non-DSP Qualcomm platforms, Google's Storm
   platform, Maxmim MAX98925 CODECs and the Ingenic JZ4780 SoC.

Currently 'Playback Volume' is the correct way to express an analogue
volume control. However, this control name has initialisation defaults
applied when using 'alsactl restore' and in some cases this is not
appropriate. An example would be a control that has a selection of
0db and -6dB of gain that is intended to set the fullscale ouput
voltage of a DAC. The TI pcm512x family of DAcs have such a control.
In this case the device/driver reset defaults are preferred.

David suggested that the name "power_mgmt" is too ambiguous.  Rename
the flag with a bit clearer one "power_save_node".

Also, add the corresponding description to HD-Audio.txt, too.

Audio timestamps can be extracted from sample counters, wall clocks,
PHC clocks (Ethernet AVB), on-demand synchronized snapshots. This
patch provides the ability to report timestamping capabilities, select
timestamp types and retrieve timestamp accuracy, if supported.
Details can be found in Documentations/sound/alsa/timestamping.txt

This functionality is introduced by reclaiming the reserved_aligned
field introduced by commit9c7066aef4a5eb8e4063de28f06c508bf6f2963a
in snd_pcm_status to provide userspace with selection/query capabilities.
Additional driver_tstamp and audio_tstamp_accuracy fields are also added.

snd_pcm_mmap_status remains a read-only structure with only
the audio timestamp value accessible from user space. The selection
of audio timestamp type is done through snd_pcm_status only

This commit does not impact ABI and does not impact the default
behavior. By default audio timestamp is aligned with hw_pointer and
reports the DMA position. Backwards compatibility is handled by using
the HDAudio wall clock for playback and the hw_ptr for all other
cases.

For timestamp selection a new STATUS_EXT ioctl is introduced with
read/write parameters. Alsa-lib will be modified to make use of
STATUS_EXT.
