Stephen Warren f726536fc0 ASoC: tegra_alc5632: assume CONFIG_OF, and other cleanup
Tegra only supports, and always enables, device tree. Remove all runtime
checks for DT support from the driver.

Also, various minor cleanups so that the probe() body more closely
resembles other drivers, for easier comparison.

Bill Pemberton 4652a0d0c4 ASoC: tegra: 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.

Stephen Warren c921928661 sound: tegra_alc5632: remove HP detect GPIO inversion
Both the schematics and practical testing show that the HP detect GPIO
is high when the headphones are plugged in. Hence, the snd_soc_jack_gpio
should not specify to invert the signal.

Stephen Warren 40db77a0c4 ASoC: tegra: remove usage of rtd->codec
rtd->codec_dai->codec can be used instead.

This is a slight step along the way to not needing the rtd->codec field

Stephen Warren bc92657a11 ASoC: make snd_soc_dai_link more symmetrical
Prior to this patch, the CPU side of a DAI link was specified using a
single name. Often, this was the result of calling dev_name() on the
device providing the DAI, but in the case of a CPU DAI driver that
provided multiple DAIs, it needed to mix together both the device name
and some device-relative name, in order to form a single globally unique
name.

However, the CODEC side of the DAI link was specified using separate
fields for device (name or OF node) and device-relative DAI name.

This patch allows the CPU side of a DAI link to be specified in the same
way as the CODEC side, separating concepts of device and device-relative
DAI name.

I believe this will be important in multi-codec and/or dynamic PCM
scenarios, where a single CPU driver provides multiple DAIs, while also
booting using device tree, with accompanying desire not to hard-code the
CPU side device's name into the original .cpu_dai_name field.

Ideally, both the CPU DAI and CODEC DAI loops in soc_bind_dai_link()
would now be identical. However, two things prevent that at present:

1) The need to save rtd->codec for the CODEC side, which means we have
to search for the CODEC explicitly, and not just the CODEC side DAI.

2) Since we know the CODEC side DAI is part of a codec, and not just
a standalone DAI, it's slightly more efficient to convert .codec_name/
.codec_of_node into a codec first, and then compare each DAI's .codec
field, since this avoids strcmp() on each DAI's CODEC's name within
the loop.

However, the two loops are essentially semantically equivalent.

Stephen Warren 9f6328d910 ASoC: tegra+alc5632: unconditionally free jack GPIOs in remove
The headphone jack GPIOs are added/initialized in the DAI link's init()
method, and hence in theory may not always have been added before remove()
is called in some unusual cases. In order to prevent calling
snd_soc_jack_free_gpios() if snd_soc_jack_add_gpios() had not been, the
code kept track of the initialization state to avoid the free call when
necessary.

However, it appears that snd_soc_jack_free_gpios() is robust in the face
of being called without snd_soc_jack_add_gpios() first succeeding, so
there is little point manually tracking this information. Hence, remove
the tracking code. All other machine drivers already operate this way.

Now that deferred probe exists, we can parse device tree and request
GPIOs from probe(), rather than deferring this to the DAI link's init().

Stephen Warren 518de86ba1 ASoC: tegra: register 'platform' from DAIs, get rid of pdev
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a
platform_device. This didn't represent the hardware well, since there
was no separate hardware associated with this platform_device; it was a
virtual device with sole purpose to call snd_soc_register_platform().
This mechanism required all board files to register this device, and all
ASoC machine drivers to create and register this device when booting
using device tree.

This change removes the platform_device completely. Each Tegra DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.
