As we want gpio_chip .get() calls to be able to return negative
error codes and propagate to drivers, we need to go over all
drivers and make sure their return values are clamped to [0,1].
We do this by using the ret = !!(val) design pattern.

The stream is created whilst the compressed stream is opened and a
buffer is created when the DSP powers up. It is necessary at a point
once both the DSP has powered up and the the stream has been opened to
connect a stream to a buffer on the DSP. This is done in the trigger
callback as this is after the DSP has been powered and obviously the
stream must be open. Note that whilst the connect is currently trivial
it is expected that this will get more complex when support for multiple
buffers/streams per DSP is added.

Add code that locates and initialises the buffer of compressed data on
the DSP if the firmware supported compressed data capture. The buffer
struct (wm_adsp_compr_buf) is kept separate from the stream struct
(wm_adsp_compr) this will allow much easier support of multiple
streams of data from the one DSP in the future, although support for
this will not be added in this patch chain.

When working with the compressed framework occasionally vendors will
use esoteric internal audio formats. For such formats it doesn't really
make sense to add an new define to the kernel as their use is not
sufficiently general.

This patch adds a new define SND_AUDIOCODEC_BESPOKE that vendors can use
in such situations.

This patch adds support to the codec driver to handle mic level
detect related IRQs, and report these to user-space using a uevent
variable.

The uevent variable string "EVENT=MIC_LEVEL_DETECT" is sent to
user-space, if the mic level detect feature is enabled, and the
audio captured at the chosen mic(s) is above a certain threshold.
User-space can then handle the event accordingly (e.g. process
audio capture stream).

This method was chosen over ALSA control notification for a couple
of reasons:

 1) There's no requirement here for a control to read state from.
    The event is the only thing that's required and of interest.
 2) tinyalsa support for control notifications does not exist so on
    platforms using this over alsa-lib there is a need to add code
    to support this event handling.

Another possible option would be to use the standard Jack reporting
framework but this really does not fit for this kind of event.

Finally, use of the input device framework is not being encouraged,
due to difficulties in enabling apps to access input devices, so
this has also been avoided.
