Recent addition of SoundWire stream state-machine checks in linux-next
have shown an existing issue with handling soundwire streams in codec drivers.
In general soundwire stream prepare/enable/disable can be called from either
codec/machine/controller driver. However calling it in codec driver means
that if multiple instances(Left/Right speakers) of the same codec is
connected to the same stream then it will endup calling stream
prepare/enable/disable more than once. This will mess up the stream
state-machine checks in the soundwire core.
Moving this stream handling to machine driver would fix this issue
and also allow board/platform specfic power sequencing.
Changes since v1:
- removed false error check while setting sruntime.

In existing setup WSA881x codec handles soundwire stream,
however DB845c and other machines based on SDM845c have 2
instances for WSA881x codec. This will force soundwire stream
to be prepared/enabled twice or multiple times.
Handling SoundWire Stream in machine driver would fix this issue.

There could be multiple instances of this codec on any platform,
so handling stream directly in this codec driver can lead to
multiple calls to prepare/enable/disable on the same SoundWire stream.

This series adds more WMA profiles and WMA decoder parameters to UAPI and
then support for these in qcom driver. It also adds FLAC and APE IDs and
decoder parameters to UAPI and then support in qcom driver
This was tested on Dragon board RB3.
Last, bump up the compressed version so that userspace can check for the
support.
Since the series touches compress uapi and asoc, it would make sense to go
thru asoc tree with acks.
Changes in v3:
- add r-b from Srini
- use macros for FLAC channel layout tags
Changes in v2:
- use bitflags for wma profiles

To help user-space with HDMI codec driver transition, both
a kernel module parameter and a kernel option were initially
provided to configure default behaviour of SOF on Intel hardware
with commit 139c7febad ("ASoC: SOF: Intel: add support for
snd-hda-codec-hdmi").
As hdac-hdmi is already now lagging in features compared to
snd-hda-codec-hdmi, move ahead with the transition and remove
the build option to select between the two, and instead default
to snd-hda-codec-hdmi if it is enabled in kernel build.
The old behaviour of using hdac-hdmi driver can still be forced
via the kernel module parameter.

Make HDMI optional for APL and later platforms. If no HDMI codec
is found on the HDA bus, the graphics side driver is missing or
correct codec driver is not part of kernel build, codec_mask
reflects this and HDMI is disabled. The DSP topology will still
have the links for HDMI, so connect these to dummy codec to avoid
failures in topology loading.
This change also fixes a kernel oops that was triggered if
sof_pcm512x was used with SOF configured to use hdac-hdmi (can be
done via "use_common_hdmi=0" or by selecting
CONFIG_SND_SOC_SOF_HDA_COMMON_HDMI_CODEC=n). This is not a supported
configuration.

Having a reverse dependency to a config that has its own additional
dependencies, is generally not recommended. And this applies to
select statements for SND_HDA_CODEC_HDMI, e.g. the case where SND_HDA
and SND_SOC_SOF_HDA are built as modules, but the machine driver is
built-in, leading to compile errors (reported as
i386-randconfig-e003-20200206).
Give up on trying to define different dependencies based on SOF/SST
selection, and simply add a "depends on" for SND_HDA_CODEC_HDMI. This
fixes the issue with randconfigs. Only downside is that SND_HDA_CODEC_HDMI
may be built unnecessarily in some cases, but this seems like the lesser
evil.

Since snprintf() returns the would-be-output size, not the actual

Function soc_tplg_dbytes_create(), calls soc_tplg_init_kcontrol() to
perform additional driver specific initialization. While
soc_tplg_init_kcontrol() ensures that component is valid before invoking
ops->control_load, there is no such check at the end of
soc_tplg_dbytes_create() where list_add() is used.
Also in quite a few places, there is reference of tplg->comp->dapm or
tplg->comp->card, without any checks for tplg->comp.
In consequence of the above this may lead to referencing NULL pointer.
