dma: Indicate residue granularity in dma_slave_caps

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

ALSA: ctxfi - Work around emu20k1 glitch to prevent buffered sound data loss

Occasionally, on playback stream ringbuffer wraparound, the EMU20K1
hardware will momentarily return 0 instead of the proper current(loop)
address. This patch handles that case, fixing the problem of playback
position corruption and subsequent loss of buffered sound data, that
occurs with some common buffering layout patterns(e.g. multiple
simultaneous output streams with differently-sized or
non-power-of-2-sized buffers).

An alternate means of fixing the problem would be to read the ca
register continuously, until two sequential reads return the same
value; however, that would be a more invasive change, has performance
implications, and isn't necessary unless there are also issues with the
value not being updated atomically in regards to individual bits or
something similar(which I have not encountered through light testing).

ASoC: imx-spdif: Use snd-soc-dummy CODEC driver to link card

This is a quick fix for the below two issues when building spdif as modules.

1) If modprobing modules in order: (Step 1) snd-soc-fsl-spdif -> (Step 2)
snd-soc-imx-spdif -> (Step 3) snd-soc-spdif-tx/rx, we will fail to create
imx-spdif card and dai link unless we rmmod snd-soc-imx-spdif and modprobe
it again due to the execution platform_driver_unregister() in probe() when
meeting -EPROBE_DEFER at Step 2.

2) After "imx-spdif sound-spdif.17: dit-hifi <-> 2004000.spdif mapping ok",
'rmmod snd-soc-imx-spdif' would cause kernel dump with warning:
WARNING: CPU: 0 PID: 1301 at /home/rmk/git/linux-rmk/fs/sysfs/dir.c:915 sysfs_hash_and_remove+0x84/0x90()
sysfs: can not remove 'dapm_widget', no directory
This should be caused by disordered resourse releasing of the whole link.
And trying to unregister the card and then CODEC dev can't fix this issue.

Thus this patch just provides a simple fix to these two bugs by using the
snd-soc-dummy in the core instead of seperate snd-soc-spdif-tx/rx so that
there's no need to handle the registering and unregistering of CODEC or
