Furthermore when McASP is in master and sync mode the capture operation

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

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

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.

The dmaengine framework now exposes the granularity with which it is able to
report the transfer residue for a certain DMA channel. Check the granularity in
the generic dmaengine PCM driver and

	b) Fallback to the (race condition prone) period counting if the driver does
	not support any residue reporting.

Currently we have two different snd_soc_platform_driver structs in the generic
dmaengine PCM driver. One for dmaengine drivers that support residue reporting
and one for those which do not. When registering the PCM component we check
whether the NO_RESIDUE flag is set or not and use the corresponding
snd_soc_platform_driver. This patch modifies the driver to only have one
snd_soc_platform_driver struct where the pointer() callback checks the
NO_RESIDUE flag at runtime. This allows us to set the NO_RESIDUE flag after the
PCM component has been registered. This becomes necessary when querying whether
the dmaengine driver supports residue reporting from the dmaengine driver itself
since the DMA channel might only be requested after the PCM component has been
registered.

This patch adds a new field to the dma_slave_caps struct which indicates the
granularity with which the driver is able to update the residue field of the
dma_tx_state struct. Making this information available to dmaengine users allows
them to make better decisions on how to operate. E.g. for audio certain features
like wakeup less operation or timer based scheduling only make sense and work
correctly if the reported residue is fine-grained enough.

Right now four different levels of granularity are supported:
	* DESCRIPTOR: The DMA channel is only able to tell whether a descriptor has
	  been completed or not, which means residue reporting is not supported by
	  this channel. The residue field of the dma_tx_state field will always be
	  0.
	* SEGMENT: The DMA channel updates the residue field after each successfully
	  completed segment of the transfer (For cyclic transfers this is after each
	  period). This is typically implemented by having the hardware generate an
	  interrupt after each transferred segment and then the drivers updates the
	  outstanding residue by the size of the segment. Another possibility is if
	  the hardware supports SG and the segment descriptor has a field which gets
	  set after the segment has been completed. The driver then counts the
	  number of segments without the flag set to compute the residue.
	* BURST: The DMA channel updates the residue field after each transferred
	  burst. This is typically only supported if the hardware has a progress
	  register of some sort (E.g. a register with the current read/write address
	  or a register with the amount of bursts/beats/bytes that have been
	  transferred or still need to be transferred).
