Move HW initialization to separate function to allow using the code without
the v4l parts. This is needed for use in the bttv driver.

We've got bug reports that the module loading stuck on Debian system
with 3.10 kernel. The debugging session revealed that the initial
registration of OSS sequencer clients stuck at module loading time,
which involves again with request_module() at the init phase. This is
triggered only by special --install stuff Debian is using, but it's
still not good to have such loops.
As a workaround, call the registration part asynchronously. This is a
better approach irrespective of the hang fix, in anyway.

ASoC: Updates for v3.11
The biggest change here is the OMAP change, these are larger than I'd
have liked but make the driver actually usable - during the merge window
OMAP removed support for non-DT OMAP4 boards but in doing so removed the
method of accessing DMA channels used by the ASoC drivers rendering them
unusuable.
Otherwise nothing exciting, the symmetric rates change for WM8978 is a
fix for the information we expose to userspace.

Commit 8f898e92aea2c24c7f379ee265d178f69ebb9c07 removed the redundant
reads of bInterfaceProtocol from the descriptors, but introduced a
regression to devices with quirks of type QUIRK_AUDIO_FIXED_ENDPOINT,
since fp->protocol is not set in setup process.
As a consequence, audio streams would not get initialized, as the
following logs show:
[ 48.923043] setting usb interface 3:1
[ 48.923056] Creating new capture data endpoint #81
[ 48.923484] 4:3:1: cannot set freq 48000 to ep 0x81
This patch sets fp->protocol in create_fixed_stream_quirk() and
resolves the regression.

ALC5505 DSP is enabled even though we don't use the features yet at
all. This results in the unnecessarily high power consumption, more
than 100mV higher. Until we implement the DSP support, better to
bypass DSP for saving more power.

Mostly the mxs system design uses saif0 mclk output as the clock source
of codec. Since the mclk is implemented as a general divider with the
saif clk as the parent clock, let's register the mclk as a basic
clk-divider to common clock framework. Then with it being a clock
provdier, clk_get() call in codec driver probe function will just work.

ad1884_fixup_hp_eapd() tries to set the NID for controlling the
speaker EAPD from the pin configuration. But the current code can't
work expectedly since it sets spec->eapd_nid before calling the
generic parser where the autocfg pins are set up.
This patch changes the function to set spec->eapd_nid after the
generic parser call while it sets vmaster hook unconditionally. The
spec->eapd_nid check is moved in the hook function itself instead.

FireWire upper layer drivers are converted from generic
struct driver.probe() and .remove()
to bus-specific
struct fw_driver.probe() and .remove().
The new .probe() adds a const struct ieee1394_device_id *id argument,
indicating the entry in the driver's device identifiers table which
matched the fw_unit to be probed. This new argument is used by the
snd-firewire-speakers driver to look up device-specific parameters and
methods. There is at least one other FireWire audio driver currently in
development in which this will be useful too.
The new .remove() drops the unused error return code.
Although all in-tree drivers are being converted to the new methods,
support for the old methods is left in place in this commit. This
allows public developer trees to merge this commit and then move to the
new fw_driver methods.

Pull drm updates from Dave Airlie:
"Okay this is the big one, I was stalled on the fbdev pull req as I
stupidly let fbdev guys merge a patch I required to fix a warning with
some patches I had, they ended up merging the patch from the wrong
place, but the warning should be fixed. In future I'll just take the
patch myself!
Outside drm:
There are some snd changes for the HDMI audio interactions on haswell,
they've been acked for inclusion via my tree. This relies on the
wound/wait tree from Ingo which is already merged.
Major changes:
AMD finally released the dynamic power management code for all their
GPUs from r600->present day, this is great, off by default for now but
also a huge amount of code, in fact it is most of this pull request.
Since it landed there has been a lot of community testing and Alex has
sent a lot of fixes for any bugs found so far. I suspect radeon might
now be the biggest kernel driver ever :-P p.s. radeon.dpm=1 to enable
dynamic powermanagement for anyone.
New drivers:
Renesas r-car display unit.
Other highlights:
- core: GEM CMA prime support, use new w/w mutexs for TTM
reservations, cursor hotspot, doc updates
- dvo chips: chrontel 7010B support
- i915: Haswell (fbc, ips, vecs, watermarks, audio powerwell),
Valleyview (enabled by default, rc6), lots of pll reworking, 30bpp
support (this time for sure)
- nouveau: async buffer object deletion, context/register init
updates, kernel vp2 engine support, GF117 support, GK110 accel
support (with external nvidia ucode), context cleanups.
- exynos: memory leak fixes, Add S3C64XX SoC series support, device
tree updates, common clock framework support,
- qxl: cursor hotspot support, multi-monitor support, suspend/resume
support
- mgag200: hw cursor support, g200 mode limiting
- shmobile: prime support
- tegra: fixes mostly
I've been banging on this quite a lot due to the size of it, and it
seems to okay on everything I've tested it on."

git://people.freedesktop.org/~danvet/drm-intel into drm-next
Last 3.11 feature pull. I have a few odds bits and pieces and fixes in my
queue, I'll sort them out later on to see what's for 3.11-fixes and what's
for 3.12. But nothing to hold this here up imo.
Highlights:
- more hangcheck work from Mika and Chris to prepare for arb robustness
- trickle feed fixes from Ville
- first parts of the shared pch pll rework, with some basic hw state
readout and cross-checking (this shuts up the confused pch pll refcount
WARN that Linus just recently forwarded)
- Haswell audio power well support from Wang Xingchao (alsa bits acked by
Takashi)
- some cleanups and asserts sprinkling around the plane/gamma enabling
sequence from Ville
- more gtt refactoring from Ben
- clear up the adjusted->mode vs. pixel clock vs. port clock confusion
- 30bpp support, this time for real hopefully

For Intel Haswell chip, HDA controller and codec have
power well dependency from GPU side. This patch added support
to request/release power well in audio driver. Power save
feature should be enabled to get runtime power saving.
There's deadlock when request_module(i915) in azx_probe.
It looks like:
device_lock(audio pci device) -> azx_probe -> module_request
(or symbol_request) -> modprobe (userspace) -> i915 init ->
drm_pci_init -> pci_register_driver -> bus_add_driver -> driver_attach ->
which in turn tries all locks on pci bus, and when it tries the one on the
audio device, it will deadlock.
This patch introduce a work to store remaining probe stuff, and let
request_module run in safe work context.

This is a preliminary work for the upcoming Haswell HDMI audio fixes.
azx_first_init() function can be safely called after the f/w loader,
since the f/w loader doesn't require the sound hardware initialization
beforehand. Moving it into azx_probe_continue() cleans up the code
flow a bit.
