Platform driver glue for SoC using eDMA3 to use dmaengine PCM.
The maximum number of periods need to be limited to 19 since the
edma dmaengine driver limits the paRAM slot use for audio at
in cyclic mode.

Machine level DAPM widgets and routes should be registered in the card's DAPM
context, rather than in the CODEC's context.

While we are at it also drop the snd_soc_dapm_enable_pin() calls, since pins are
enabled by default and also turn the snd_soc_dapm_disable_pin() calls into
snd_soc_dapm_nc_pin() calls for unconnected pins.

These registers can be configured synchronously for playback and capture.
Furthermore when McASP is in master and sync mode the capture operation
needs the TX path to be configured in order to be able to provide the needed

ASoC: Last updates for the merge window

A couple more fixes plus some extensions to DPCM for use with compressed
audio from Liam which arrived just after my previous pull request.

The prefix for the codec driver can be used during dual identical
codec usecases. However, dapm adds prefix twice for codec DAI widget
in snd_soc_dapm_add_route API.

This change is to avoid double prefix addition for codec DAI widget
and is needed while using identical dual codecs.

Currently compressed audio streams are statically routed from the /dev
to the DAI link. Some DSPs can route compressed data to multiple BE DAIs
like they do for PCM data.

Add support to allow dynamically routed compressed streams using the existing
DPCM infrastructure. This patch adds special FE versions of the compressed ops
that work out the runtime routing.

When we plug a 3-ring headset on some Dell machines, the headset
mic can't be detected, after apply this patch, the headset mic
can work well on all those machines.

On the machine with the Subsytem ID 0x10280610, if we use
ALC269_FIXUP_DELL1_MIC_NO_PRESENCE, the headset mic can be
detected and work well, but the sound can't be outputed via
headphone anymore, use ALC269_FIXUP_DELL3_MIC_NO_PRESENCE
can fix this problem.

The Samsung dmaengine ASoC driver is used with two different dmaengine drivers.
The pl80x, which properly supports residue reporting and the pl330, which
reports that it does not support residue reporting. So there is no need to
manually set the NO_RESIDUE flag. This has the advantage that a proper (race
condition free) PCM pointer() implementation is used when the pl80x driver is
used. Also once the pl330 driver supports residue reporting the ASoC PCM driver
will automatically start using it.

The pl330 driver properly reports that it does not have residue reporting
support, which means the PCM dmanegine driver is able to figure this out on its
own. So there is no need to set the flag manually. Removing the flag has the
advantage that once the pl330 driver gains support for residue reporting it will
automatically be used by the generic dmaengine PCM driver.
