'struct snd_timer_gparams' includes some members with 'unsigned long',
therefore its size differs depending on data models of architecture. As
a result, x86/x32 applications fail to execute ioctl(2) with
SNDRV_TIMER_GPARAMS command on x86_64 machine.
This commit fixes this bug by adding a pair of structure and ioctl

The previous pull request introduced a few WARN_ON() for Intel
HD-audio HDMI. Indeed it caught bugs, and now users get annoyed.
So this request came up: a collection of small fixes to paper over
the inconsistencies on (mostly) old Intel chipsets.
In addition, a trivial USB-audio quirk is included, too.

The recent addition of on-demand i915 audio component binding in the
codec driver seems leading to the unbalanced i915 power refcount,
according to Intel CI tests. Typically, it gets a kernel WARNING
like:
WARNING: CPU: 3 PID: 173 at sound/hda/hdac_i915.c:91 snd_hdac_display_power+0xf1/0x110 [snd_hda_core]()
Call Trace:

[<ffffffffa01192a6>] hda_codec_runtime_suspend+0x76/0xa0 [snd_hda_codec]
.....
The scenario is like below:
- HD-audio driver and i915 driver are probed concurrently at the
(almost) same time; HDA bus tries to bind with i915, but it fails
because i915 initialization is still being processed.
- Later on, HD-audio probes the HDMI codec, where it again tries to
bind with i915. At this time, it succeeds.
- At finishing the probe of HDA, it decreases the refcount as if it
were already bound at the bus probe, since the component is bound
now. This triggers a kernel WARNING due to the unbalance.
As a workaround, in this patch, we just disable the on-demand i915
component binding in the codec driver. This essentially reverts back
to the state of 4.4 kernel.
We know that this is no real solution, but it's a minimalistic simple
change that can be applied to 4.5.x kernel as stable.

snd_hdac_sync_audio_rate() call is mandatory only for HSW and later
models, but we call the function unconditionally blindly assuming that
the function doesn't do anything harmful. But since recently, the
function checks the validity of the passed pin NID, and eventually
spews the warning if an unexpected pin is passed. This is seen on old
chips like Baytrail.
The fix is to limit the call of this function again only for the chips
with the proper binding. This can be identified by the same flag as
the eld notifier.

The commit [b62232d429: ALSA: hda - Limit i915 HDMI binding only for
HSW and later] tried to limit the usage of i915 audio notifier to the
recent Intel models and switch to the old method on pre-Haswell
models. However, it assumed that the i915 component binding hasn't
been done on such models, and the assumption was wrong: namely,
Baytrail had already the i915 component binding due to powerwell
control. Thus, the workaround wasn't applied to Baytrail.
For fixing this properly, this patch introduces a new flag indicating
the usage of audio notifier and codec_has_acomp() refers to this flag
instead of checking the existence of audio component.

The dummy component is reused for all cards so we special case and don't
bind it to any of them. This means that code like that displaying the
component widgets that tries to look at the card will crash. In the
future we will fix this by ensuring that the dummy component looks like
other components but that is invasive and so not suitable for a fix.
Instead add a special case check here.

The recent change in HD-audio HDMI/DP codec driver for allowing the
dynamic PCM binding introduced a new spec->pcm_mutex. One of the
protected area by this mutex is hdmi_present_sense(). As reported by
Intel CI tests, unfortunately, the new mutex causes a deadlock when
the hotplug/unplug is triggered during the codec is in runtime
suspend. The buggy code path is like the following:
hdmi_unsol_event() -> ...
-> hdmi_present_sense()
==> ** here taking pcm_mutex
-> hdmi_present_sense_via_verbs()
-> snd_hda_power_up_pm() -> ... (runtime resume calls)
-> generic_hdmi_resume()
-> hdmi_present_sense()
==> ** here taking pcm_mutex again!
As we can see here, the problem is that the mutex is taken before
snd_hda_power_up_pm() call that triggers the runtime resume. That is,
the obvious solution is to move the power up/down call outside the
mutex; it is exactly what this patch provides.
The patch also clarifies why this bug wasn't caught beforehand. We
used to have the i915 audio component for hotplug for all Intel chips,
and in that code path, there is no power up required but the
information is taken directly from the graphics side. However, we
recently switched back to the old method for some old Intel chips due
to regressions, and now the deadlock issue is surfaced.

It turned out that the pre-HSW Intel chips are incompatible with the
naive assumption we had -- the fixed mapping between the port and the
HD-audio widget. This may result in the bad access, as captured by
the recent patch to add a WARN_ON() for the port mapping check.
As a quick workaround, disable the i915 audio component binding for
all pre-Haswell models.

Cirrus HD-audio driver may adjust GPIO pins for EAPD dynamically
depending on the jack plug state. This works fine for the auto-mute
mode where the speaker gets muted upon the HP jack plug. OTOH, when
the auto-mute mode is off, this turns off the EAPD unexpectedly
depending on the jack state, which results in the silent speaker
output.
This patch fixes the silent speaker output issue by setting GPIO bits
constantly when the auto-mute mode is off.

gcc warns about the possibilty of accessing a property read from

sound/soc/codecs/cs35l32.c:278:2: warning: 'val' may be used uninitialized in this function [-Wmaybe-uninitialized]
The code is actually correct because it checks the dev->of_node
variable first and we know this is NULL here when CONFIG_OF
is disabled, but Russell King noticed that it's broken when
we probe the device using DT, and the properties are absent.
The code already has some checking for incorrect values, and
I keep that checking unchanged here, but add an additional
check for an error returned by the property accessor functions
that now gets handled the same way as incorrect data in the
properties.

This is far too big a set of fixes for this late in the release cycle
but the overwhelming bulk is essentially the same simple fix from
Takashi for a cut'n'pasted 64 bit cleanliness issue in the userspace
interface where drivers were accessing things using the wrong element in
a union which worked OK on 32 bit platforms as the correct element
happened to be aligned the same way but with 64 bit platforms ABIs are
different and the two members of the union are laid out in different
places. They aren't all tagged to stable since some of these chips have
vanishingly little chance of being used in 64 bit systems.
The other changes are:
- A fix for Qualcomm devices to work on big endian systems. The
original change is actually correct but triggered a bug in regmap
which is too invasive to fix for this cycle and can be worked around
by just letting regmap pick the default.
- A fix for the Samsung I2S driver locking which wasn't using IRQ safe
spinlocks when it needed to.
- A fix for the new Intel Sky Lake driver forgetting that C pointer
arithmetic takes the type of the pointer into consideration.
- A revert of a change to the FSL SSI driver that broke some systems.
- A fix for the cleanup path of the wm9713 driver.
- A fix for some incorrect register definitions in the ADAU17x1 driver
that caused misclocking in some configurations.
- A fix for the tracepoints for jack detection to avoid using an
internal field of the core jack structure which is no longer present
in all configurations.
- A fix for another of the new Intel drivers which tried to write to a

Some models reduce the number of available isochronous streams for higher
sampling transfer frequency. Such models bring an issue about how to add
PCM substreams. When at lower sampling transfer frequency, the
models reports whole available streams, thus this driver can add enough
number of PCM substreams at probing time. On the other hand, at higher
sampling transfer frequency, this driver can just add reduced number of
PCM substreams. After probed, even if the sampling transfer frequency is
changed to lower rate, fewer PCM substreams are actually available. This
is inconvenience.
For the reason, this commit adds a list so that this driver assume models
on the list to have two pairs of PCM substreams. This list keeps the name
of model in which the number of available streams differs depending on
sampling transfer frequency.

In former commits, ALSA dice driver can handle available isochronous
streams. This commit adds support for several PCM substreams on the
streams.
The additional PCM substreams are available via another ALSA PCM character
devices so that one ALSA PCM application can handle them without cumbersome
operations. For example, two PCM substreams are available on each stream,
two ALSA character devices are added for them. In configuration space of
alsa-lib, it's represented with 'hw:0,0' and 'hw:0,1'.
The PCM substreams are constraint to parameters of the corresponding
streams. If the PCM substreams are unavailable for some reasons,
open(2) to ALSA PCM character device returns error and reports ENXIO.

Currently ALSA dice driver handles a pair of isochronous resources for
IEC 61883-1/6 packet streaming. While, according to some documents about
ASICs named as 'Dice', several isochronous streams are available.
Here, I start to describe ASICs produced under 'Dice' name.
* Dice II (designed by wavefront semiconductor, including TCAT's IP)
* STD (with limited functionality of DTCP)
* CP (with full functionality of DTCP)
* TCD2210/2210-E (so-called 'Dice Mini')
* TCD2220/2220-E (so-called 'Dice Jr.')
* TCD3070-CH (so-called 'Dice III')
Some documents are public and we can see hardware design of them. We can
find some articles about hardware internal register definitions
(not registers exported to IEEE 1394 bus).
* DICE II User Guide
* http://www.tctechnologies.tc/archive/downloads/dice_ii_user_guide.pdf
* 6.1 AVS Audio Receivers
* Table 6.1: AVS Audio Receiver Memory Map
* ARX1-ARX4
* 6.2 AVS Audio Transmitters
* Table 6.2: AVS Audio Transmitter Memory Map
* ATX1, ATX2
* TCD22xx User Guide
* http://www.tctechnologies.tc/downloads/tcd22xx_user_guide.pdf
* 6.1 AVS Audio Receivers
* Table 66: AVS Audio Receiver Memory Map
* ARX1, ARX2
* 6/2 AVS Audio Transmitters
* Table 67: AVS Audio Transmitter Memory Map
* ATX1, ATX2
* DICE III
* http://www.tctechnologies.tc/downloads/TCD3070-CH.pdf
* Dual stream 63 channel transmitter/receiver
For Dice II and TCD22xx series, maximum 16 data channels are transferred in
an AMDTP packet, while for Dice III, maximum 32 data channels are
transferred.
According to the design of the series of these ASICs, this commit allows
this driver to handle additional set of isochronous resources. For
practical reason, two pair of isochronous resources are added. As of this
commit, this driver still use a pair of the first isochronous resources.

Rename dma_*_writecombine() to dma_*_wc(), so that the naming
is coherent across the various write-combining APIs. Keep the
old names for compatibility for a while, these can be removed
at a later time. A guard is left to enable backporting of the
rename, and later remove of the old mapping defines seemlessly.
Build tested successfully with allmodconfig.
The following Coccinelle SmPL patch was used for this simple
transformation:
@ rename_dma_alloc_writecombine @
expression dev, size, dma_addr, gfp;
@@
-dma_alloc_writecombine(dev, size, dma_addr, gfp)
+dma_alloc_wc(dev, size, dma_addr, gfp)
@ rename_dma_free_writecombine @
expression dev, size, cpu_addr, dma_addr;
@@
-dma_free_writecombine(dev, size, cpu_addr, dma_addr)
+dma_free_wc(dev, size, cpu_addr, dma_addr)
@ rename_dma_mmap_writecombine @
expression dev, vma, cpu_addr, dma_addr, size;
@@
-dma_mmap_writecombine(dev, vma, cpu_addr, dma_addr, size)
+dma_mmap_wc(dev, vma, cpu_addr, dma_addr, size)
We also keep the old names as compatibility helpers, and
guard against their definition to make backporting easier.

Introduce PCI_VENDOR/PCI_SUBVENDOR/PCI_SUBDEVICE defines to replace the
constants scattered in the kernel already used to detect QEMU.
They are defined in the QEMU codebase per docs/specs/pci-ids.txt.

rawmidi devices expose the card number via IOCTLs, which allows to
find the corresponding device in sysfs.
The sequencer provides no identifing data. Chromium works around this
issue by scanning rawmidi as well as sequencer devices and matching
them by using assumtions, how the kernel register sequencer devices.
This changes adds support for exposing the card number for kernel clients
as well as the PID for user client.
The minor of the API version is changed to distinguish between the zero
initialised reserved field and card number 0.

HD-audio driver has a mechanism to trigger the runtime resume
automatically at accessing the verbs. This auto-resume, however,
causes the mutex deadlock when invoked from the regmap handler since
the regmap keeps the mutex while auto-resuming. For avoiding that,
there is some tricky check in the HDA regmap handler to return -EAGAIN
error to back-off when the codec is powered down. Then the caller of
regmap r/w will retry after properly turning on the codec power.
This works in most cases, but there seems a slight race between the
codec power check and the actual on-demand auto-resume trigger. This
resulted in the lockdep splat, eventually leading to a real deadlock.
This patch tries to address the race window by getting the runtime PM
refcount at the check time using pm_runtime_get_if_in_use(). With
this call, we can keep the power on only when the codec has been
already turned on, and back off if not.
For keeping the code consistency, the code touching the runtime PM is
stored in hdac_device.c although it's used only locally in
hdac_regmap.c.

Chmap helper arguments are modified to use either hdac_device
object or hdac_chmap object instead of codec specific object.
With this moving these APIs to core will be easier.
Helper added to access a specific channel_allocation object
instead of directly accessing.
