This SPDIF transmitter/receiver is used by the HifiBerry DIGI+ and
DIGI IO. The wm8804 operates as bit clock and frame master.
TODO in future update: add support for capture on the DIGI+ IO (this
may be done with a different topology file to avoid confusing users
with a non-working PCM capture patch)

This patch decreases pipeline buffers usage from 5x or 4x periods to 3x
to avoid DAI error in APL platform when allocating buffers. The smaller
buffers are sufficient since the test topology pipelines are scheduled
every 1ms (earlier assumption was every 5 ms).
The PCM capability is updated to 8 channels similarly as with low delay
pipeline. The highest sample rate is increased from 96 kHz to 192 kHz.

The APL and GLK topologies are identical except for a swap of SSPs and MCLKs.
Tested on Reef and GLK
TODO:
1. there is currently a kernel bug where only duplex pipelines can be
assigned to the same PCM number. For now mark DMIC as device 99 to
track this is a work-around to be modified in the near future
2. Edit the Virtual routes/widgets to remove kernel warnings (no
functional impact)

PR43 and commit dc10876c20 ('topology: changes to SectionPCM

between pcm id and dummy dai id. Tested on APL/Reef Chromebook

This patch addresses the following:
1. Move PCM_PLAYBACK_ADD to pcm.m4
The macro was in the wrong m4 file (buffer.m4)
2. Remove pipeline_id argument and "index" from SectionPCM
"index" is not a member of struct snd_soc_tplg_pcm. So this
information is not used in the kernel at all.
Secondly, the PCM ID could be associated with more than
one pipeline especially in the case of DUPLEX PCM's. So better
to remove it to avoid ambiguities.
3. Remove dai_id
This dai_id is the ID given to the CPU DAI when the FE DAI link
is created. In the case of SOF, we should use an linearly increasing
unique ID for CPU DAI ID's. If this argument is omitted, the kernel
automatially assignes an ID based on the component->num_dai
which is linearly incremented every time a new DAI link is added.
4. Finally update users to align with the new definitions.

This patch extends the allowed sample rate range to 8 - 192 kHz, and
channels count to 1 - 16. Previously only 48 kHz and 2 - 4 channels was
allowed.

This patch increases the SRC source buffer to contain 5 periods of data
(measured for 1 ms @ 48 kHz ). It fixes the issue in 176.4 kHz to 48 kHz
playback conversion that the pipeline freezes with insufficient available
data in source buffer for SRC to convert and too little free in buffer
for host to fill another 48 frames.
176.4 kHz playback is currently the largest buffer size consumer due
to non-steady in/out rate. The higher rate conversion 192 kHz to 48 kHz
can operate with smaller size buffer due to steady in/out rate.
Note: This has been only simulated in the host test bench since SRC
playback does not run currently in real devices due to another issue.
However since buffers simulation is accurate this should be a real issue.
