ASoC: simple-card: Don't create separate link when platform is present
In normal sound case all DAIs are detected as CPU-Codec.
simple_dai_link_of supports the presence of a platform but it counts
it as a CPU DAI resulting in the creation of an extra link.

Adding a platform property to a link description like:

simple-audio-card,dai-link {
	cpu {
		sound-dai = <&sai1>;
	};
	plat {
		sound-dai = <&dsp>;
	};
	codec {
		sound-dai = <&wm8960>;
	}

will result in the creation of two links:
	* sai1 <-> wm8960
	* dsp  <-> wm8960

which is obviously not what we want. We just want one single link
with:
	* sai1 <-> wm8960 (and platform set to dsp).

ASoC: simple-card: indicate rebind issue
ALSA SoC try to rebind Sound Card if Card/CPU/Codec/Platform
were unbinded and re-binded again.
But, Simple Card might can't rebind again if user do for example

	unbind CPU or Codec driver
	bind   CPU or Codec driver

Because Simple Card is still pointing old/unbinded
CPU or Codec driver's DAI name at dlc->dai_name.

To avoid this issue, it needs to alloc memory and keep DAI name
even though if CPU or Codec driver was unbinded.
Or, always do unbind/bind at Sound Card.

For now, this patch indicates this issue as FIXME.

ASoC: simple-card: Restore original configuration of DAI format
Revert commit 069d037aea ("ASoC: simple-card: Fix configuration of
DAI format"). During further review, it turns out that the actual issue
was caused by an incorrectly formatted device-tree node describing the
soundcard.

The following is incorrect because the simple-audio-card
'bitclock-master' and 'frame-master' properties should not reference the
actual codec phandle ...

	sound {
		compatible = "simple-audio-card";
		...
	=>	simple-audio-card,bitclock-master = <&codec>;
	=>	simple-audio-card,frame-master = <&codec>;
		...

		simple-audio-card,cpu {
			sound-dai = <&xxx>;
		};

		simple-audio-card,codec {
	=>		sound-dai = <&codec>;
		};
	};

Rather, these properties should reference the phandle to the
'simple-audio-card,codec' property as shown below ...

	sound {
		compatible = "simple-audio-card";
		...
	=>	simple-audio-card,bitclock-master = <&codec>;
	=>	simple-audio-card,frame-master = <&codec>;
		...

		simple-audio-card,cpu {
			sound-dai = <&xxx>;
		};

	=>	codec: simple-audio-card,codec { /* simple-card wants here */
			sound-dai = <&xxx>;	 /* not here */
		};
	};

ASoC: simple-card: Fix configuration of DAI format
When configuring a codec to be both bit-clock and frame-master, it was
found that the codec was always configured as bit-clock and frame-slave.
Looking at the simple_dai_link_of() function there appears to be two
problems with the configuration of the DAI format, which are ...

1. The function asoc_simple_parse_daifmt() is called before the function
   asoc_simple_parse_codec() and this means that the device-tree node
   for the codec has not been parsed yet, which is needed by the
   function asoc_simple_parse_daifmt() to determine who is the codec.
2. The phandle passed to asoc_simple_parse_daifmt() is the phandle to
   the 'codec' node and not the phandle of the actual codec defined by
   the 'sound-dai' property under the 'codec' node.

Fix the above by moving the call to asoc_simple_parse_daifmt() after the
the call to asoc_simple_parse_codec() and pass the phandle for the codec
to asoc_simple_parse_daifmt().

ASoC: simple-card: don't select DPCM via simple-audio-card
commit da215354eb ("ASoC: simple-card: merge simple-scu-card")
merged simple-scu-audio-card which can handle DPCM into
simple-audio-card.

By this patch, the judgement to select "normal sound card" or
"DPCM sound card" is based on its CPU/Codec DAI count.
But, because of it, existing "simple-audio-card" user who is
assuming "normal sound card" might select DPCM unintentionally.

To solve this issue, this patch allows "simple-audio-card" user
can select "normal sound card", and "simple-scu-audio-card" user
can select both "normal sound card" and "DPCM sound card".
This keeps compatibility collectry.

ASoC: simple_card_utils: share common priv for simple-card/audio-graph
Historically, simple-card/simple-scu-card/audio-graph/audio-graph-scu
are similar but different generic sound card.
simple-scu-card which was for DPCM was merged into simple-card, and
audio-graph-scu which was for DPCM was merged into audio-graph.
simple-card is for non OF graph sound card, and
audio-graph is for     OF graph sound card.
And, small detail difference (= function parameter, naming, etc)
between simple-card/audio-graph has been unified.

So today, the difference between simple-card/audio-graph are
just using OF graph style, or not.
In other words, there should no difference other than OF graph sytle.
simple-card/audio-graph are using own priv today , but we can merge it.

ASoC: simple-card: Fix of-node refcount unbalance in DAI-link parser
The function simple_for_each_link() has a few missing places that
forgot unrefereing of-nodes after the use.  The main do-while loop
may abort when loop=0, and this leaves the node object still
referenced.  A similar leak is found in the error handling of NULL
codec that aborts the loop as well.  Last but not least, the inner
for_each_child_of_node() loop may abort in the middle, and this leaks
the refcount of the iterator node.

so far. We will need to have multi Platform support in the not far

Currently only simple card is using it as sound card driver,
and other drivers are converted to it from legacy style by
snd_soc_init_platform().
To avoid future problem of multi Platform support, let's add
num_platforms before it is too late.

In the same time, to make it same naming mothed, "platform" should

ASoC: simple-card: cleanup DAI link loop method - step1
Current simple-card is parsing DAI link for both "normal sound" and
"DPCM sound". On this driver, it needs to count and parse
DAIs/Links/Codec Conf from each links.
Then, counting/parsing link loop are very similar, but using different
implementation. Because of this background, the link loop code is very
mysterious. Mystery code will be trouble in the future.

This patch adds/modifies counting and parsing function for
"normal sound" and "DPCM sound", and call it from link loop.
This is prepare for cleanup DAI link loop method.

ASoC: simple-card: add link_info

Then, counting/parsing link loop are very similar, but using different

To preparing cleanup code, this patch adds link_info which handles
number of DAIs/Links/Codec Conf, and CPU/Codec turn.

ASoC: simple-card: add 1 CPU : 1 Codec support again
simple-card is now supporting normal sound and DPCM sound.
For DPCM sound, original sound card (= simple-scu-card) had been
supported 1 CPU : 1 Codec connection which uses hw_params_fixup()
for convert-rate/channel.
But, merged simple-card is completely forgeting about it.

This patch re-support it.

For DPCM sound, original sound card (= simple-scu-card) had been

But, merged simple-card is completely forgeting about it.

To re-support 1 CPU : 1 Codec DPCM for hw_params_fixup(),
it need to judge whether it is DPCM by checking convert-rate/channel.
For this purpose, this patch adds asoc_simple_card_get_conversion()
as preparation

It will be overwrote if lower node has it.

ASoC: simple-card: merge simple-scu-card
simple-card and simple-scu-card are very similar driver,
but the former is supporting normal sound card,
the latter is supporting DPCM sound card.

We couldn't use normal sound and DPCM sound in same time by
one sound card. This patch merges both sound card into
simple-card. Now we can use both feature on same driver.

simple-card is now supporting .compatible = "simple-scu-audio-card".

ASoC: simple-card: use cpu/codec pointer on simple_dai_props
In  DPCM case, it uses CPU-dummy / dummy-Codec dai links, and
non DPCM case, it uses CPU-Codec dai links.

Now, we want to merge simple-card and simple-scu-card.

These sound cards are using silimar but not same logic on each functions.
Then, of course we want to share same logic.
To compromise, this patch uses cpu/codec pointer on simple-card.
It is same logic with simple-scu-card, thus easy merging.
This is prepare for merging audio card
