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.

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.

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.
