Peter Ujfalusi 1d69c5c5de ASoC: core: Add flag to ignore pmdown_time at pcm_close
With this flag codec drivers can indicate that it is desired
to ignore the pmdown_time for DAPM shutdown sequence when
playback stream is stopped.
The DAPM sequence will be executed without delay in this case.

Dong Aisheng 17841020e9 ASoC: soc-core: symmetry checking for each DAIs separately
The orginal code does not cover the case that one DAI such as codec
may be shared between other two DAIs(CPU).
When do symmetry checking, altough the codec DAI requires symmetry,
the two CPU DAIs may still be configured to run on different rates.

We change to check each DAI's state separately instead of only checking
the dai link to prevent this issue.

Sascha Hauer 25b7679136 ASoC: Fix check for symmetric rate enforcement
The ASoC core tries to not enforce symmetric rates when
two streams open simultaneously. It does so by checking
rtd->rate being zero. This works exactly once after booting
because it is not set to zero again when the streams close.
Fix this by setting rtd->rate when no active stream is left.

[This leads to lots of warnings about not enforcing the symmetry in some
situations as there's a race in the userspace API where we know we've
got two applications but don't know what rates they want to set.

Axel Lin 6fc562e49c ASoC: soc-pcm: Remove unused global mutex
Since commit b8c0dab9bf
"ASoC: core - PCM mutex per rtd",
the global pcm_mutex is not being used any more.

Liam Girdwood 91d5e6b4f5 ASoC: pcm - rename snd_codec_close() to snd_pcm_close().
Make sure we follow naming convention for all PCM ops.

Liam Girdwood b8c0dab9bf ASoC: core - PCM mutex per rtd
In preparation for the new ASoC Dynamic PCM support (AKA DSP support).

The new ASoC Dynamic PCM core allows DAIs to be dynamically re-routed
at runtime between the PCM device end (or Frontend - FE) and the physical DAI
(Backend - BE) using regular kcontrols (just like a hardware CODEC routes
audio in the analog domain). The Dynamic PCM core therefore must be
able to call PCM operations for both the Frontend and Backend(s) DAIs at
the same time.

Currently we have a global pcm_mutex that is used to serialise
the ASoC PCM operations. This patch removes the global mutex
and adds a mutex per RTD allowing the PCM operations to be reentrant and
allow control of more than one DAI at at time. e.g. a frontend PCM hw_params()
could configure multiple backend DAI hw_params() with similar or different
hw parameters at the same time.

Liam Girdwood ddee627cf6 ASoC: core - Separate out PCM operations into new file.
In preparation for Dynamic PCM support (AKA DSP support).

There will be future patches that add support to allow PCMs to be dynamically
routed to multiple DAIs at startup and also during stream runtime. This patch
moves the ASoC core PCM operaitions into a new file called soc-pcm.c.  This will
in simplify the ASoC core features into distinct files.
