ASoC: simple-card-utils: Make simple_util_remove() return void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code.  However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.

simple_util_remove() returned zero unconditionally. Make it return void
instead and convert all users to struct platform_device::remove_new().

ASoC: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

ASoC: audio-graph-card2: add comment for format property
We don't need to have "format" property on DT any more if

ASoC: simple-card: add comment to indicate don't remove platforms
Basically CPU and Platform are different Component, but if CPU is using
soc-generic-dmaengine-pcm, same dev will be shared between CPU and
Platform, and Simple Card had been supporting it.

When we focus to clean up Simple Card driver, we tend to remove platforms
if no Platform was selected, but it is wrong because of above reasons.

This patch adds comment why we shouldn't remove platforms.

In case of CPU is not using soc-generic-dmaengine-pcm, CPU and Platform
will be duplicated, but it will be ignored by snd_soc_rtd_add_component().

ASoC: Use of_property_present() for testing DT property presence
It is preferred to use typed property access functions (i.e.
of_property_read_<type> functions) rather than low-level
of_get_property/of_find_property functions for reading properties. As
part of this, convert of_get_property/of_find_property calls to the
recently added of_property_present() helper when we just want to test
for presence of a property and nothing more.

ASoC: audio_graph_card2: Add support for variable slot widths
Some audio hardware cannot support the same slot width for all sample
widths, or a slot width equal to the sample width for all sample widths.
This is usually due either to limitations of the audio serial port or
system clocking restrictions.
A typical example would be:

- 16-bit samples in 16-bit slots
- 24-bit samples in 32-bit slots

The new dai-tdm-slot-width-map property allows setting a mapping of
sample widths and the corresponding tdm slot widths and slot counts.
Although the slot count is usually the same for all cases this does
allow for adding padding slots to maintain the same bitclk frequency.

The property is added to each endpoint node that needs the component
DAI to be told the TDM slot width and count.

ASoC: audio-graph-card2: add Codec2Codec support
This patch adds Codec2Codec support to audio-graph-card2.
It can use Codec2Codec but very simple case only for now.
It doesn't have "SWITCH" control yet, thus it start automatically
when it was probed, and can't stop, so far.
Thus it needs to be updated around widgets/routing handling,
and you need to understand that it is under experimental.

Codec has SND_SOC_DAPM_INPUT() (= IN) / SND_SOC_DAPM_OUTPUT(= OUT)
widgets in below case.

It is assuming 2channel, S32_LE format for now.
It needs to be updated, too.

It needs "codec2codec" node (= B), needs to have routing (= A),
need to indicate CPU side at links (= X).
ports@0 is for CPU side (= X), port@1 is Codec side (= Y).
It needs to have "rate" (= C)

6e5f68fe3f
ASoC: add Audio Graph Card2 driver
We already have audio-graph-card which is Of-graph base of general
sound card driver.

It is supporting DPCM connection, but was forcibly expanded.
Thus, it is very difficult to add new features on it, for example
Multi CPU/Codec support, Codec2Codec support, etc.

This patch adds more flexible new Audio Graph Card2 driver for it.
audio-graph-card and audio-graph-card2 are similar, but don't have
full compatibility.

Audio Graph Card2 supports very generic connection, but some users
want to have its own settings, for example PLL settings, etc.
For such case, it has customizing support.
In users own driver, it can use Audio Graph Card2 parsing by using
audio_graph2_parse_of(), and doing its own customizing.

Because Audio Graph Card2 is still under experimental stage,
it will indicate such warning when probing, and the DT syntax
might be changed.
