Wolfram Sang ab31135e6e ASoC: : drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Liam Girdwood bece9e957c ASoC: utils: Add internal call to determine if DAI is dummy.
Provide a quick way to tell if a DAI is a dummy DAI or a regular DAI.
This is for internal DAPM usage only and is used to determine whether to
insert a DAI link connection into the DAPM graph.

Lars-Peter Clausen 95ab1297e7 ASoC: soc-utils: Don't set unused struct snd_pcm_hardware fields
The ASoC core assumes that the PCM component of the ASoC card transparently
moves data around and does not impose any restrictions on the memory layout or
the transfer speed. It ignores all fields from the snd_pcm_hardware struct for
the PCM driver that are related to this. Setting these fields in the PCM driver
might suggest otherwise though, so rather not set them.

Stas Sergeev 60b6f1a1e5 ASoC: define playback and capture streams in dummy codec
This patch adds a playback and capture streams to the dummy codec DAI
configuration. Most permissive set of sampling rates and formats is used.

This patch is needed for playback and capturing on a codec-less systems,
as otherwise the PCM device nodes are not even created.

Bill Pemberton e51e97eecd ASoC: utils: remove __dev* attributes
CONFIG_HOTPLUG is going away as an option.  As result the __dev*
markings will be going away.

Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst,
and __devexit.

Liam Girdwood 7aca69f9fe ASoC: utils - Add support for a dummy codec driver.
This is useful to create dummy codec devices where we need to have some
DAI links without a real Codec. e.g. could be used to represent dumb FM,
MODEM, etc

This is also used by dynamic PCM for DAI links that have no codec.

Mark Brown cefcc03ffc ASoC: Provide a more complete DMA driver stub
Allow userspace applications to do more parameter setting by providing a
more complete stub DMA driver specifying a wildcard set of formats and
channels and essentially random values for the DMA parameters. This is
required for useful runtime operation of the dummy DMA driver until we
are able to figure out how to power up links and do hw_params() from DAPM.

Sending to stable as without this the dummy driver is not terribly
useful.

Paul Gortmaker d81a6d7176 sound: Add export.h for THIS_MODULE/EXPORT_SYMBOL where needed
These aren't modules, but they do make use of these macros, so
they will need export.h to get that definition.  Previously,
they got it via the implicit module.h inclusion.

Mark Brown 848dd8beef ASoC: Add more natural support for no-DMA DAIs
Since we can now support multiple platforms allow machines to not specify
a platform in a DAI link. Since the rest of the code requires that we have
a struct device for all objects we do this by substituting in a dummy
device that we register automatically.
