We had inserted a #error into the topology UAPI code to ensure that the
ABI was not adopted by userspace while final review and testing was
ongoing. The idea was that some finishing touches would be made to the
ABI before declaring it stable and suitable for use in production but
this has not yet happened as more than a year later revisions to the ABI
are still onging.The reality however is that people are shipping topology files in
production and these ABI changes are causing practical issues for users
and we can't break userspace. This makes this error pointless so we
should remove it.Signed-off-by: Mark Brown

ASoC: Updates for v4.9
Apart from the cleanups done by Morimoto-san this has very much been a
driver focused release with very little generic change:- A big factoring out of the simple-card code to allow it to be shared
more with the rcar generic card from Kuninori Morimoto.
- Removal of some operations duplicated on the CODEC level, again by
Kuninori Morimoto.
- Lots more machine support for x86 systems.
- New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.

In commit bf1d1c9b6179 ("ALSA: tlv: add DECLARE_TLV_DB_RANGE()"), the new
macro was added so that "dB range information can be specified without
having to count the items manually for TLV_DB_RANGE_HEAD()". In short,
TLV_DB_RANGE_HEAD macro was obsoleted.In commit 46e860f76804 ("ALSA: rename TLV-related macros so that they're
friendly to user applications"), TLV-related macros are exposed for
applications in user land to get content of data structured by
Type/Length/Value shape. The commit managed to expose TLV-related macros
as many as possible, while obsoleted TLV_DB_RANGE_HEAD() was included to
the list of exposed macros.This situation brings some confusions to application developers because
they might think all exposed macros have their own purpose and useful for
applications.For the reason, this commit moves TLV_DB_RANGE_HEAD macro from UAPI header
to a header for kernel land, again. The above commit is done within the
same development period for kernel 4.9, thus not published yet. This
commit might certainly brings no confusions to user land.Reference: commit bf1d1c9b6179 ("ALSA: tlv: add DECLARE_TLV_DB_RANGE()")

We must do it this way, because e.g. POD X3 won't play any sound unless
the host listens on the bulk EP, so we cannot export it only via libusb.The driver currently doesn't use the bulk EP messages in other way,
in future it could e.g. sense/modify volume(s).Signed-off-by: Andrej Krutak

In a previous commit, some macros newly appeared to UAPI header for TLV
packet. These macros have short names and they easily bring name conflist
to applications. The conflict can be avoided to rename them with a proper
prefix.For this purpose, this commit renames these macros with prefix
'SNDRV_CTL_TLVD_'.Signed-off-by: Takashi Sakamoto

In ALSA control interface, each element set can have threshold level
information. This information is transferred between drivers/applications,
in a shape of tlv packet. The layout of this packet is defined in
'uapi/sound/asound.h' (struct snd_ctl_tlv):struct snd_ctl_tlv {
unsigned int numid;
unsigned int length;
unsigned int tlv[0];
};Data in the payload (struct snd_ctl_tlv.tlv) is expected to be filled
according to our own protocol. This protocol is described in
'include/sound/tlv.h'. A layout of the payload is expected as:struct snd_ctl_tlv.tlv[0]: one of SNDRV_CTL_TLVT_XXX
struct snd_ctl_tlv.tlv[1]: Length of data
struct snd_ctl_tlv.tlv[2...]: dataUnfortunately, the macro is not exported to user land yet, thus
applications cannot get to know the protocol.Additionally, ALSA control core has a feature called as 'user-defined'
element set. This allows applications to add/remove arbitrary element sets
with elements to control devices. Elements in the element set can be
operated by the same way as the ones added by in-kernel implementation.For threshold level information of 'user-defined' element set, applications
need to register the information to an element set. However, as described
above, layout of the payload is closed in kernel land. This is quite
inconvenient, too.This commit moves the protocol to UAPI header for TLV.

With recent topology changes in alsa-lib, driver data for

the conf file.In the topology conf file, multiple data blocks can be defined
for a widget which can be either tuple vendor array or blob. So,
each data block will be preceded by a descriptor to identify
size and type of block. These descriptors will be token
value pairs.Tokens for module_id and loadable flag are not defined as these

ASoC: Updates for v4.7 part 2
Really sorry about this late pull request. It looks like at the time I
sent my pull request for v4.7 there was some conflict or other issue
which caused my script to stop merging the ASoC branches at some point
after the HDMI changes.It's all specific driver updates, including:
- New drivers for MAX98371 and TAS5720.
- SPI support for TLV320AIC32x4.
- TDM support for STI Uniperf IPs.This code should all have been in -next prior to the merge window apart
from some fixes, it dropped out on the 18th.

Tuples, a pair of token and value, can be used to define vendor specific
data, for controls and widgets. This can avoid importing binary data blob
from other files.Vendor specific tuple arrays will be embeded in the private data buffer
of a control or widget object. To be backward compatible, union is used
to define the tuple arrays in the existing private data ABI object
'struct snd_soc_tplg_private'.Vendors need to make sure the token values defined by the topology conf
file match those defined by their driver.Now supported tuple types are uuid, string, bool, byte, short and word.

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.[minor coding style fixes by tiwai]

Digi 002/003 family uses asynchronous transaction for messaging.
The address to transmit this message is stored on a certain register.This commit allocates a range of address on OHCI 1394 host controller
to handle the messaging. As long as I know, the purpose of this message
seems to notify lost of synchronization. While, the meaning of content
of the message is not clear.Actual examples of this messaging:
* When clock source is set as internal:
- 0x00007051
- 0x00007052
- 0x00007054
- 0x00007057
- 0x00007058
* When clock source is set as somewhat external:
- 0x00009000
- 0x00009010
- 0x00009020
- 0x00009021
- 0x00009022The lost often occurs when using internal clock source. In this case,
users hear sounds with quite short gap every several minutes. In fact,
the lost is recovered temporarily.When using with external clock source, the lost seems not to occur. The
mechanism is not clear yet.Signed-off-by: Takashi Sakamoto

ASoC: Disable topology support for v4.2
The topology code merged in the v4.2 merge window introduced a new ABI
which was believed to be suitable for use but subsequently additional
work by the developers of this feature have revealed some problems that
need to be addressed. In order to allow this to be done without having
to support the initial ABI add Kconfig to disable the build and also add
some #error statements to the UAPI header so users can't use them.

Since the topology API is still in sufficient flux for changes to be
