ASoC: Samsung: Do not register samsung audio dma device as 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 change removes the platform_device completely. Each Samsung DAI now
registers the ASoC 'platform' itself. Machine drivers are adjusted for
the new 'platform' name.

ASoC: McASP: implement a way to force BCLK/LRCLK ratios
Depending on the Codec, the the BCLK/LRCLK ratio might not be freely
chosen by the CPU DAI.
For example, some Codec might want to be supplied with 32-bit samples
for both its channels regardless of the actual audio word size the CPU
sends. In such cases, the rest of the bits on the data lines must be
padded with zeros:
DATA ____||||||||||||||||_________________|||||||||| .....
|<-- data -->|<-- pads --> |
This patch adds a new clock divider to configure the BCLK/LRCLK ratio.
If the machine code uses that divider, the driver uses the specified
value, instead of deriving that information from the audio word size.
Otherwise, the original behaviour is retained.

ASoC: McASP: calculate values for channel size
Change davinci_config_channel_size() to derive the values for XSSZ and
XROT in DAVINCI_MCASP_[RT]XFMT_REG from the configured word length
rather than hard-coding them in a switch/case block.
Also, by directly passing the word length to
davinci_config_channel_size(), we can get rid of the
DAVINCI_AUDIO_WORD_* enum.

The machine driver try to use GPIO15 of twl4030 for HS MUX which supposed to

Also the current machine driver supports only TWL audio currently: there is

ASoC: wm8994: Simplify button detection code
Currently the WM8994 driver allows the WM8958 microphone detection code to
be replaced in its entirety, providing a default implementation. This
doesn't actually reflect the needs of users well. They generally wish to
replace only the accessory identification parts of the algorithm (eg,
using an external GPIO to provide the equivalent of the JACKDET support in
the WM1811A).
In preparation for supporting these users better refactor the existing code
so that we have separate identification and button detection callbacks,
selecting between them rather than using the mic_detecting flag in the
existing callback. This also simplifies the code by introducing a more
explicit state machine for the detecting and button states.
In anticipation of future refactoring the callback is left in the signature
for wm8958_mic_detect(), it will be removed at a later stage.
