 "This time we have dmatest improvements from Andy along with dw_dmac
  fixes.  He has also done support for acpi for dmanegine.

  Also we have bunch of fixes going in DT support for dmanegine for
  various folks.  Then Haswell and other ioat changes from Dave and
  SUDMAC support from Shimoda."

at_hdmac: move to generic DMA binding

2013-04-30T08:47:41+00:00

Update at_hdmac driver to support generic DMA device tree binding. Devices
can still request channel with dma_request_channel() then it doesn't break
DMA for non DT boards.

dmaengine: at_hdmac: fix race condition in atc_advance_work()

2013-04-18T15:54:22+00:00

The BUG_ON() directive is triggered probably due to a latency
modification following inclusion of commit c10d73671ad3 ("softirq:
reduce latencies").  This condition has not been met before 3.9-rc1 and
doesn't trigger without this patch.

We now make sure that DMA channel is idle before calling
atc_complete_all() which makes the BUG_ON() "protection" useless.

dma: at_hdmac: check direction properly for cyclic transfers

2013-01-12T13:07:21+00:00

dma_transfer_direction is a normal enum. It means we can't usually use the
values as bit fields. Let's adjust this check and move it above the usage of
the direction parameter, due to the nature of the following usage of it.

Merge tag 'sound-3.7' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

2012-10-08T22:07:14+00:00

Pull sound updates from Takashi Iwai:
"This contains pretty many small commits covering fairly large range of
files in sound/ directory. Partly because of additional API support
and partly because of constantly developed ASoC and ARM stuff.

Some highlights:

- Introduced the helper function and documentation for exposing the
channel map via control API, as discussed in Plumbers; most of PCI
drivers are covered, will follow more drivers later

- Most of drivers have been replaced with the new PM callbacks (if
the bus is supported)

- HD-audio controller got the support of runtime PM and the support
of D3 clock-stop. Also changing the power_save option in sysfs
kicks off immediately to enable / disable the power-save mode.

- Another significant code change in HD-audio is the rewrite of
firmware loading code. Other than that, most of changes in
HD-audio are continued cleanups and standardization for the generic
auto parser and bug fixes (HBR, device-specific fixups), in
addition to the support of channel-map API.

- Addition of ASoC bindings for the compressed API, used by the
mid-x86 drivers.

- Lots of cleanups and API refreshes for ASoC codec drivers and
DaVinci.

- Conversion of OMAP to dmaengine.

- New machine driver for Wolfson Microelectronics Bells.

- New CODEC driver for Wolfson Microelectronics WM0010.

- Enhancements to the ux500 and wm2000 drivers

- A new driver for DA9055 and the support for regulator bypass mode."

Fix up various arm soc header file reorg conflicts.

dmaengine: Pass flags via device_prep_dma_cyclic() callback

2012-09-22T15:12:45+00:00

Change the parameter list of device_prep_dma_cyclic() so the DMA drivers
can receive the flags coming from clients.
This feature can be used during audio operation to disable all audio
related interrupts when the DMA_PREP_INTERRUPT is cleared from the flags.

Log message is for debug only because this condition is unlikely to
