The Wolfson Arizona series of audio hub CODECs can share a large amount
of their driver code as the result of a common register map. This patch
adds some of this core support, providing a basis for the initial WM5102
audio driver.

Currently the sound dmaengine pcm helper functions implement the pcm_pointer
callback by trying to count the number of elapsed periods. This is done by
advancing the stream position in the dmaengine callback by one period.
Unfortunately there is no guarantee that the callback will be called for each
elapsed period. It may be possible that under high system load it is only called
once for multiple elapsed periods. This patch addresses the issue by
implementing support for querying the current stream position directly from the
dmaengine driver. Since not all dmaengine drivers support reporting the stream
position yet the old period counting implementation is kept for now.

Furthermore the new mechanism allows to report the stream position with a
sub-period granularity, given that the dmaengine driver supports this.

Unfortunately there is no guarantee that the callback will be called for each

and documents its shortcomings and that it should not be used anymore in new
drivers.

The next patch will introduce a new snd_dmaengine_pcm_pointer which will be
implemented based on querying the current stream position from the dma device.

This patch adds a small inline wrapper for the devivce_tx_status callback of a
dma device. This makes the source code of users of this function a bit more
compact and a bit more legible.

E.g.:
-status = chan->device->device_tx_status(chan, cookie, &state)
+status = dmaengine_tx_status(chan, cookie, &state)

soc_probe_dai_link() currently inter-mixes the probing of CODECs,
platforms, and DAIs. This can lead to problems such as a CODEC's DAI
being probed before the CODEC, if that DAI is used as the CPU-side of
a DAI link without any other of the CODEC's DAIs having been used as
the CODEC-side of any DAI link that was probed earlier.

To solve this, split soc_probe_dai_link() into soc_probe_link_components()
and soc_probe_link_dais(). The former is used to probe all CODECs and
platforms used by a card first, and then the latter is used to probe all
the DAIs and links later.

A similar change is made to soc_remove_dai_links().

This change simply factors out part of soc_remove_dai_link() into a

When a standalone CPU DAI (one not part of a CODEC) is probed, widgets
are created for it. Add a call to snd_soc_dapm_free() in order to clean
these up when the CPU DAI is removed.

In order for snd_soc_dapm_free() to work, the CPU DAI's DAPM context's
list member must be initialized, since snd_soc_dapm_free() removes that
from the list it's part of. Add it to the card's list of DAPM contexts.

If the CPU-side of a DAI link is a CODEC rather than a standalone DAI,
the codec initialization will call try_module_get() and create the DAI
widgets. Ensure that this isn't duplicated when the CPU DAI itself is
probed, if the CPU DAI is part of a CODEC.

Note that this is not a complete fix on its own, since there's no
guarantee that the CODEC itself will be initialized - currently that only
happens if the CODEC is also used as the CODEC-side of a DAI link, and
that initialization may happen before or after the DAIs within the CODEC
are initialized. However, such a scenario doesn't necessarily currently
work, and I don't think this change alone makes it any worse. This is
fixed in a couple patches time.
