08f9f4485f ALSA: core api: define offsets for TLV items
Currently, there are no pre-defined accessors for the elements
in topology TLV data. In the absence of such offsets, the
tlv data will have to be decoded using hardwired offset
numbers 0-N depending on the type of TLV. This patch defines
accessor offsets for the type, length, min and mute/step items
in TLV data for DB_SCALE type tlv's. These will be used by drivers to
decode the TLV data while loading topology thereby improving
code readability. The type and len offsets are common for all TLV
types. The min and step/mute offsets are specific to DB_SCALE tlv type.

2e48b2b7a2 ALSA: hda/ca0132: Add extra exit functions for R3Di and SBZ
This patch adds extra functions for shutdown on the Sound Blaster Z and
Recon3Di. The Recon3Di only has one specific functions, which sets the
GPIO data pins to 0 to prevent a popping noise.

The Sound Blaster Z exit sequence was taken from Windows. Without this
exit function, the card will not reload properly unless the PC has been
shutdown to clear the onboard memory. There are commented out functions
currently in the sbz_exit_chip function that are added in a later patch.

Also, a reboot notify function has been added, to make sure these
functions are ran before a reboot. This helps when using the card
through VFIO in a virtual machine, to make sure the card reloads the DSP
properly.

4120fbedbb ALSA: usb-audio: Add "Keep Interface" control
This patch adds "Keep Interface" control for each USB-audio device.
The control element is with SND_CTL_IFACE_CARD, so that it won't
appear on any sane mixer applications.  For a device that is confirmed
to work well with "keep-interface" mode, user can flip the control via
amixer, e.g.
  % amixer -c1 cset iface=CARD,name='Keep Interface' on

and save/restore the state via alsactl.

The reason to provide this via control API is that the behavior must
be pretty depending on the device (and the firmware in it), so it's
not ideal to apply via module option.

For a device that certainly works, we may set it statically via a
quirk table entry.  But a device like Dell WD15 dock behaves so
differently depending on the firmware, and we can't set it
statically.  So leave this as a dynamic switch each user can adjust
freely.

8a463225b1 ALSA: usb-audio: Add keep_iface flag
Introduce a new flag to struct snd_usb_audio for allowing the device
to skip usb_set_interface() calls at changing or closing the stream.
As of this patch, the flag is nowhere set, so it's just a place
holder.  The dynamic switching will be added in the following patch.

A background information for this change:

Dell WD15 dock with Realtek chip gives a very long pause at each time
the driver changes the altset, which eventually happens at every PCM
stream open/close and parameter change.  As the long pause happens in
each usb_set_interface() call, there is nothing we can do as long as
it's called.  The workaround is to reduce calling it as much as
possible, and this flag indicates that behavior.

9c367c01d3 ALSA: dice: remove local frag of force_two_pcms
At present, to add PCM substreams for each of available tx/rx streams,
this driver uses a condition based on model-name. This is not enough
to support unknown models.

In former commits, this driver gains cache of stream formats. For models
which support protocol extension, all of available steam formats are
cached. For known models, hard-coded stream formats are used to generate
the cache. For unknown models, stream formats at current mode of sampling
transmission frequency is cached.

Anyway, at least, the cached formats are used to expose constrains of PCM
substreams for userspace applications. Thus, The cached data can be also
used to add PCM substreams themselves, instead of the name-based
conditions.

b7fd3d64e7 ALSA: dice: add proc node for stream formation
Products with DICE interface in market can support variable stream
formats for three levels of sampling transmission frequencies. To
record these formats, a proxy structure got several fields in former
commit.

This commit adds a proc node to output the stream formats for debugging
purpose.

37149d6687 ALSA: dice: add 'firewire' directory for proc nodes
Unlike the other drivers in ALSA firewire stack, ALSA dice driver does't
create 'firewire' directory for proc nodes because it has 'dice' node
only. But this is inconvenient because I have a plan to add another proc
node to output available stream formats from cache.

This commit let the driver to create the directory and put 'dice' node
into it.

8feda7ddb6 ALSA: dice: add cache of stream formats
A previous commit 6f688268b3 ('ALSA: dice: purge generating channel
cache') purged cache of stream formats. DICE interface originally has
no feature to assist drivers to retrieve available formats for all of
supported sampling transmission frequencies, without changing the
frequency actually.

For later release of Dice ASICs such as TCD2210, Dice interface has
extended protocol and can support the feature. This assists drivers
to retrieve available stream formats.

This commit is a first step to regain the cache to generate PCM rules
for all of supported sampling transmission frequencies.

8e142e9e62 ALSA: hda/ca0132: fix build failure when a local macro is defined
DECLARE_TLV_DB_SCALE (alias of SNDRV_CTL_TLVD_DECLARE_DB_SCALE) is used but
tlv.h is not included. This causes build failure when local macro is
defined by comment-out.

This commit fixes the bug. At the same time, the alias macro is replaced
with a destination macro added at a commit 46e860f768 ("ALSA: rename
TLV-related macros so that they're friendly to user applications")

f4a414aa6e ALSA: hda - Enforce CONFIG_SND_DYNAMIC_MINORS for HDMI/DP codec
The DP-MST support requires more PCM streams than usual, hence
CONFIG_SND_DYNAMIC_MINORS is almost mandatory.  Currently the driver
just warns and continues even if streams are missing, but it doesn't
seem to enough convince users to switch to the modern setup.

This patch adds the enforced selection of CONFIG_SND_DYNAMIC_MINORS
from CONFIG_SND_HDA_CODEC_HDMI for covering that.

8a7d6003df ALSA: hda - Skip jack and others for non-existing PCM streams
When CONFIG_SND_DYNAMIC_MINORS isn't set, there are only limited
number of devices available, and HD-audio, especially with HDMI/DP
codec, will fail to create more than two devices.

The driver warns about the lack of such devices and skips the PCM
device creations, but the HDMI driver still tries to create the
corresponding JACK, SPDIF and ELD controls even for the non-existing
PCM substreams.  This results in confusion on user-space, and even may
break the operation.

Similarly, Intel HDMI/DP codec builds the ELD notification from i915
graphics driver, and this may be broken if a notification is sent for
the non-existing PCM stream.

This patch adds the check of the existence of the assigned PCM
substream in the both scenarios above, and skips the further operation
if the PCM substream is not assigned.
