6ff67ccafd ASoC: topology: ABI - Add voice wake up flag for DAI links
Add a new flag bit SND_SOC_TPLG_LNK_FLGBIT_VOICE_WAKEUP to link flags.
If a link is used for voice wake up, users can set this flag bit and
topology will set the link's 'ignore_suspend' to true.

This ABI update is backward compatible.

9aa3f03473 ASoC: topology: Rename functions & variables for physical DAIs
Code refactoring. These functions and variables are for configuring
physical DAIs, not only backend DAIs since users may not need DPCM.
So remove 'be' from the function names, and rename variables 'be'
to 'd' or 'dai'.

3fbf793510 ASoC: topology: ABI - Rename struct and type for physical DAIs
Rename the ABI struct and type because they are for configuring physical
DAIs, not only backend DAIs since users may not need DPCM:
- Rename struct snd_soc_tplg_be_dai to snd_soc_tplg_dai.
- Rename type SND_SOC_TPLG_TYPE_BE_DAI to SND_SOC_TPLG_TYPE_DAI.

This code refactoring is backward compatible because:
- Both layout of the struct and type value has no change. Kernel can
  find the same type value and map to same data layout.
- This struct is not in ABI v4 at all. Now the user space uses ABI v4.

717a8e7235 ASoC: topology: ABI - Add flags and private data to PCM
This is the remaining update to PCM ABI object of version 5.

The flags will be applied to FE (Front End) links and can also be used
by physical links. The private data is reserved for future extension, so
offset update will add the private data size.

Now user space is using ABI v4, and the previous patch "ASoC: topology:
make PCM backward compatible from ABI v4" can assure the backward
compatibility.

Users start to use topology ABI from v4. ABI v5 updated existing manifest

55726dc95b ASoC: topology: Make PCM backward compatible from ABI v4
This patch adds support for old version 4 of PCMs (FE DAI & DAI links).

Topology ABI v5 added new fields to stream caps and thus changed PCMs.
Since user space may still uses v4, kernel will check the ABI version by
comparing the object size. If user space uses v4 of PCMs, kernel will
create the latest version of PCMs from the old version, and use the new
version internally to create FE DAI & DAI links. Because these new created
PCM elements will be freed later, kernel need duplicate the name strings
of DAI driver and DAI links when creating them.

Currently the TLV topology structure is targeted at only supporting the
DB scale data. This patch extends support for the other TLV types so they
can be easily added at a later stage.

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.

Added TLV structure to generic control header and removed TLV structure
from mixer control.
