b7c9d85205 ALSA: ASoC: Don't suggest compile time selection of codec access
Currently the boiler plate code used by most ASoC codecs to provide a
placeholder for SPI access suggests making the selection of SPI a
compile time option which is suboptimal when trying to build kernels
supporting multiple systems.  Change this template to suggest allowing
runtime selection instead.

Leave the drivers not yet converted to new style I2C access for now to
avoid collisions.

e5d3fd38f9 ALSA: ASoC: Convert wm8990 to a new-style i2c driver
Convert the wm8990 codec driver to the new (standard) device driver
binding model. After this change, WM8990 devices are no longer
discovered automatically and must instead be instantiated explicitly.

3051e41ab7 ALSA: ASoC: Fix double free and memory leak in many codec drivers
Many SoC audio codec drivers have improper freeing of memory in error
paths.

* codec is allocated in the platform device probe function, but is not
  freed there in case of error. Instead it is freed in the i2c device
  probe function's error path. However the success or failure of both
  functions is not linked, so this could result in a double free (if
  the platform device is successfully probed, the i2c device probing
  fails and then the platform driver is unregistered.)

* codec->private_data is allocated in many platform device probe
  functions but not freed in their error paths.

This patch hopefully solves all these problems.

97bb8129e5 ALSA: wm8990: Implement speaker volume PGA
The latest revisions of the WM8990 provide a programmable gain amplifier
for the speaker - configure the register cache and implement controls
for this. Older revisions of the device ignore writes to these controls.

e550e17ffe ALSA: asoc: codecs - merge structs snd_soc_codec_dai and snd_soc_cpu_dai.
This patch merges struct snd_soc_codec_dai and struct
snd_soc_cpu_dai into struct snd_soc_dai for the codec drivers.

a5c95e90c1 ALSA: ASoC: Replace custom debug macros with pr_ equivalents
Several ASoC codec drivers use custom macros equivalent to the standard
pr_ macros, most of which are not actually used. Replace these custom
macros with the standard ones.

f10485e798 [ALSA] ASoC: Add WM8990 driver
The WM8990 is a highly integrated ultra-low power hi-fi codec designed
for handsets rich in multimedia features such as mobile TV, digital
audio playback and gaming.

The bulk of this driver was written by Liam Girdwood with some
additional development and updates for new ASoC APIs by me.
