2016-10-11ASoC: topology: Reenable use from userspaceMark Brown
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 <broonie@kernel.org> Acked-by: Vinod Koul <vinod.koul@intel.com>

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next 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.

2016-09-25ALSA: control: cage TLV_DB_RANGE_HEAD in kernel land because it was obsoletedTakashi Sakamoto
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.

2016-09-19ALSA: line6: Add hwdep interface to access the POD control messagesAndrej Krutak
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).

2016-09-15ALSA: rename TLV-related macros so that they're friendly to user applicationsTakashi Sakamoto
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_'.

2016-09-15ALSA: control: move layout of TLV payload to UAPI headerTakashi 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...]: data Unfortunately, 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.

2016-08-22ASoC: uapi: Intel: Skylake: Define vendor specific tokensShreyas NC
With recent topology changes in alsa-lib, driver data for modules can now be passed in topology conf file using tuples. This patch defines vendor specific tokens to describe private data with tuples. The allowed token types are UUID, string, bool, byte, short and word. These tokens will be referenced by the vendor tuples in 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 are read from the DSP FW manifest.

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus 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.

2016-03-29ASoC: topology: ABI - Define types for vendor tuplesMengdong Lin
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.

2016-03-08ALSA: seq: Provide card number / PID via sequencer client infoMartin Koegler
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.

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 - 0x00009022 The 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 <o-takashi@sakamocchi.jp> Signed-off-by: Takashi Iwai <tiwai@suse.de>

TLV structure is moved to common topology control header since it's a common field for controls and can be processed in a general way. Users must set a proper access flag for a control since it's used to decide if the TLV field is valid and if a TLV callback is needed. Removed the following fields from topology TLV struct: - size/count: type can decide the size. - numid: not needed to initialize TLV for kcontrol. - data: replaced by the type specific struct.
