ASoC: soc-card: Create jack kcontrol without pins

snd_soc_card_jack_new() allowed to create jack kcontrol without pins,
but did not create kcontrols. The jack would not have kcontrols if pins
were not going to be added.

This renames the old snd_soc_card_jack_new() to
snd_soc_card_jack_new_pins() for use when pins are provided or will be
added later. The new snd_soc_card_jack_new() appropriately creates a
jack for use without pins and adds a kcontrol.

ASoC: Allow to register jacks at the card level

Jacks are typically card level elements, but are currently registered with a
CODEC. When it was originally introduced snd_soc_jack_new() took a
snd_soc_card as its parameter, but at that time DAPM was only implemented at
the CODEC level and there was only one CODEC per card. This made it clear
which CODEC to use for the jack DAPM operations. But the multi-component
patchset added support for having multiple CODECs per card and with it the
API was updated to register jacks with a specific CODEC instance instead.
Subsequently DAPM support at the card level has been introduced, but the
snd_soc_jack_new() API has so remained unchanged.

This leaves us with the issue that the DAPM pins that are managed by the
jack detection logic usually are part of the card DAPM context but are
accessed through a CODEC DAPM context. Currently this works fine, but might
break in the future if we take a more hierarchical approach to DAPM
contexts.

Furthermore with componentization progressing systems that do not register
a snd_soc_codec might appear, while these system may still want to able to
register a jack.

This patch addresses these issues by adding a new function called
snd_soc_card_jack_new() that can be used to register jacks with the card
rather than a CODEC.

This new function is mostly identical to snd_soc_jack_new() except that it
additionally allows to directly specify the DAPM pins associated with the
jack. This was done since most users of snd_soc_jack_new() typically call
snd_soc_jack_add_pins() right after it, which is not necessary with the new
API and allows to reduce the amount of boiler plate code.

The old snd_soc_jack_new() is re-implemented as a wrapper around
snd_soc_card_jack_new().

create a per jack lock to take care of the jack status.

ASoC: multi-component - ASoC Multi-Component Support

This patch extends the ASoC API to allow sound cards to have more than one
CODEC and more than one platform DMA controller. This is achieved by dividing
some current ASoC structures that contain both driver data and device data into
structures that only either contain device data or driver data. i.e.

struct snd_soc_codec ---> struct snd_soc_codec (device data)
+-> struct snd_soc_codec_driver (driver data)

struct snd_soc_platform ---> struct snd_soc_platform (device data)
+-> struct snd_soc_platform_driver (driver data)

struct snd_soc_dai ---> struct snd_soc_dai (device data)
+-> struct snd_soc_dai_driver (driver data)

struct snd_soc_device ---> deleted

This now allows ASoC to be more tightly aligned with the Linux driver model and
also means that every ASoC codec, platform and (platform) DAI is a kernel
device. ASoC component private data is now stored as device private data.

The ASoC sound card struct snd_soc_card has also been updated to store lists
of it's components rather than a pointer to a codec and platform. The PCM
runtime struct soc_pcm_runtime now has pointers to all its components.

This patch adds DAPM support for ASoC multi-component and removes struct
snd_soc_socdev from DAPM core. All DAPM calls are now made on a card, codec
or runtime PCM level basis rather than using snd_soc_socdev.

Other notable multi-component changes:-

* Stream operations now de-reference less structures.
* close_delayed work() now runs on a DAI basis rather than looping all DAIs
in a card.
* PM suspend()/resume() operations can now handle N CODECs and Platforms
per sound card.
* Added soc_bind_dai_link() to bind the component devices to the sound card.
* Added soc_dai_link_probe() and soc_dai_link_remove() to probe and remove
DAI link components.
* sysfs entries can now be registered per component per card.
* snd_soc_new_pcms() functionailty rolled into dai_link_probe().
* snd_soc_register_codec() now does all the codec list and mutex init.

This patch changes the probe() and remove() of the CODEC drivers as follows:-

o Make CODEC driver a platform driver
o Moved all struct snd_soc_codec list, mutex, etc initialiasation to core.
o Removed all static codec pointers (drivers now support > 1 codec dev)
o snd_soc_register_pcms() now done by core.
o snd_soc_register_dai() folded into snd_soc_register_codec().

ASoC: Allow reporting of NULL jacks

Follow the core jack implementation and allow reporting on the status
of NULL jacks, avoiding the need to check in detection implementations.

ASoC: Add a notifier for jack status changes

Some systems provide both mechanical and electrical detection of jack
status changes. On such systems power savings can be achieved by only
enabling the electrical detection methods when physical insertion has
been detected.

Begin supporting such systems by providing a notifier for jack status
changes which can be used to trigger any reconfiguration.

ASoC: Add jack_status_check callback function for GPIO jacks

The jack_status_check callback function is the interface to check the
status of the jack. Some target provides the method to distinguish what
is the jack inserted - headphone jack, microphone jack, tvout jack, etc,
so we can implement it using the jack_status_check function.

ASoC: Move dereference after NULL test

If the NULL test on jack is needed, then the derefernce should be after the
NULL test.

A simplified version of the semantic match that detects this problem is as
follows (http://coccinelle.lip6.fr/):

// <smpl>
@match exists@
expression x, E;
identifier fld;
@@

* x->fld
... when != \(x = E\|&x\)
* x == NULL
// </smpl>

ASoC: jack: Fix race in snd_soc_jack_add_gpios

The irq can fire as soon as it has been requested, thus all fields accessed
from within the irq handler must be initialized prior to requesting the irq.

ASoC: Jack handling enhancements as suggested by subsystem maintainer

The patch adds a few small enhancements to the ASoC jack handling, as
suggested by Mark in his comments to my Amstrad Delta driver, and a few fixes
for related bugs found while learning Mark's code and testing results.

Enhancements:
1. Update status of an ASoC jack while associating it with new gpios.
2. Really update DAPM pins while associating them with an ASoC jack.
3. Export ASoC jack gpios over gpiolib sysfs for diagnostic purposes.

Fixes:
1. Apply mask on jack status report before using it, just for case.
2. While updating jack associated DAPM pins, use full resulting jack status,
not the status report passed as an argument.

Created and tested on linux-2.6.31-rc3

ASoC: Add GPIO support for jack reporting interface

Add GPIO support to jack reporting framework in ASoC using gpiolib calls.
The gpio support exports two new functions: snd_soc_jack_add_gpios and
snd_soc_jack_free_gpios.

Client drivers using gpio feature must pass an array of jack_gpio pins
belonging to a specific jack to the snd_soc_jack_add_gpios function. The
framework will request the gpios, set the data direction and request irq.
The framework will update power status of related jack_pins when an event on
the gpio pins comes according to the reporting bits defined for each gpio.

All gpio resources allocated when adding jack_gpio pins can be released
using snd_soc_jack_free_gpios function.

ASoC: Add jack reporting interface

This patch adds a jack reporting interface to ASoC. This wraps the ALSA
core jack detection functionality and provides integration with DAPM to
automatically update the power state of pins based on the jack state.

Since embedded platforms can have multiple detecton methods used for a
single jack (eg, separate microphone and headphone detection) the report
function allows specification of which bits are being updated on a given
report.

The expected usage is that machine drivers will create jack objects and
then configure jack detection methods to update that jack.
