This adds a driver for the HDA block in Tegra SoCs. The HDA bus is
used to communicate with the HDMI codec on Tegra124.Most of the code is re-used from the Intel/PCI HDA driver. It brings
over only two of the module params, power_save and probe_mask.Signed-off-by: Dylan Reid

We have currently sysfs attributes for each hwdep, but basically these
should belong to the codec itself, per se. Let's add them to the
codec object while keeping them for hwdep as is for compatibility.While we are at it, split the sysfs-related stuff into a separate
source file, hda_sysfs.c, and keep only the stuff necessary for hwdep
in hda_hwdep.c.Signed-off-by: Takashi Iwai

When a Kconfig of a codec driver doesn't match with the controller
(CONFIG_SND_HDA_INTEL), it'll result in the non-working automatic
probing. Unfortunately kbuild can't give such a restriction, but at
least, it's possible to show a warning if such a condition is found.Signed-off-by: Takashi Iwai
-
So far, CONFIG_SND_HDA_CODEC_* kconfigs have been booleans due to
historical reasons. The major reason was that the automatic codec
driver probing wouldn't work if user sets a codec driver as a module
while the controller driver as a built-in. And, another reason was to
avoid exporting symbols of the helper codes when all drivers are built
in.But, this sort of "kindness" rather confuses people in the end,
especially makes the config refinement via localmodconfig unhappy.
Also, a codec module would still work if you re-bind the controller
driver via sysfs (although it's no automatic loading), so there might
be a slight use case.That said, better to let people fallen into a pitfall than being too
smart and restrict something. Let's make things straightforward: now
all CONFIG_SND_HDA_CODEC_* become tristate, and all symbols exported
unconditionally.Signed-off-by: Takashi Iwai

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 mostlyI've been banging on this quite a lot due to the size of it, and it

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.Signed-off-by: Wang Xingchao

Currently HDMI codec driver sets the hard dependency (reverse
selection) on CONFIG_SND_DYNAMIC_MINORS because the recent codecs may
support more than two PCMs. But, this doesn't mean that we need
always this option, since there can be a single PCM stream even with
the modern codecs.This patch drops the hard dependency again but give more sensible
error message when no enough PCMs are available due to the lack of
this option.Signed-off-by: Takashi Iwai

Finally we reached here. All codecs driver (except for CA0132, which
has really device-specific requirements) have been converted to use
the generic parser.This patch appears bigger than others since it also involves with the
code shuffling, but mostly the cut-off of parser codes and adapt to
the generic parser flags. Most of fixup codecs haven't been changed
but just removed a few unnecessary codes.The only missing stuff is the SPDIF mux control. It'll be added again
later.Signed-off-by: Takashi Iwai

This patch adds the support for the generic auto-parser to AD codec
driver. For AD1988, the old code is replaced simply with the new
generic parser. For other codecs, new model "auto" is added and
directed to use the generic parser.No fixup codes have been implemented yet as of now. Eventually we'd
replace each static quirk with the generic parser + fixup.Signed-off-by: Takashi Iwai

This time, the target is Cirrus codec. Its parser is a subset of
generic parser, so we can migrate fully with it now.The only tricky part is the handling of SPDIF automute.

other) mute.Signed-off-by: Takashi Iwai

The beep_mode=2 option was introduced to make the beep mixer
controlling the beep input allocation/deallocation dynamically, so
that a user can switch between HD-audio codec digital beep and the
system beep only via mixer API. This was necessary because the
keyboard driver took only the first input beep instance at that time.However, the recent keyboard driver already processes the multiple
input instances, thus there is no point to keep this mode.Let's remove it.

By setting this off, all quirk codes won't be built, thus you can save

This patch merges all three patch_*hdmi variants to the single HDMI
parser. There is only one snd-hda-codec-hdmi module now.In this patch, the behavior of each parser isn't changed much.
The old ATI parser still doesn't use the dynamic parser yet.
In later patches, they'll be cleaned up.Also, this patch gets rid of the individual snd-hda-eld module and
builds into snd-hda-codec-hdmi, since this is referred only from the
HDMI parser.Signed-off-by: Takashi Iwai
