ASoC: audio-graph-card.c: move audio_graph_parse_of()
Current audio-graph-card functions definition are like below

(A)'	static int graph_get_dais_count();

(B)	int audio_graph_parse_of(...)
	{
		...
(A)		ret = graph_get_dais_count();
		...
	}

(A)	static int graph_get_dais_count(...)
	{
		...
	}
(C)

We don't need to have (A)' definition if audio_graph_parse_of() (B) was
defined at (C). This patch moves (B) to (C).

ASoC: audio-graph-card2: add comment for format property
We don't need to have "format" property on DT any more if
CPU/Codec driver has .auto_selectable_formats settings
on snd_soc_dai_ops. The sample dtsi doesn't have it.
To avoid user confusion, this patch indicates it on comment.

ASoC: soc-dai.h: merge DAI call back functions into ops
snd_soc_dai_driver has .ops for call back functions (A), but it also
has other call back functions (B). It is duplicated and confusable.

This patch merges (B) into (A).

ASoC: simple-card-utils: fix PCM constraint error check
The code in asoc_simple_startup was treating any non-zero return from
snd_pcm_hw_constraint_minmax as an error, when this can return 1 in some
normal cases and only negative values indicate an error.

When this happened, it caused asoc_simple_startup to disable the clocks
it just enabled and return 1, which was not treated as an error by the
calling code which only checks for negative return values. Then when the
PCM is eventually shut down, it causes the clock framework to complain
about disabling clocks that were not enabled.

Fix the check for snd_pcm_hw_constraint_minmax return value to only
treat negative values as an error.

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: generic: test-component: Convert to platform remove callback returning 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.

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

ASoC: simple-card: Fix up checks for HW param fixups
The "convert-xxx" properties only have an effect for DPCM DAI links.
A DAI link is only created as DPCM if the device tree requires it;
part of this involves checking for the use of "convert-xxx" properties.

When the convert-sample-format property was added, the checks got out
of sync. A DAI link that specified only convert-sample-format but did
not pass any of the other DPCM checks would not go into DPCM mode and
the convert-sample-format property would be silently ignored.

Fix this by adding a function to do the "convert-xxx" property checks,
instead of open-coding it in simple-card and audio-graph-card. And add
"convert-sample-format" to the check function so that DAI links using
it will be initialized correctly.

ASoC: simple-card-utils.c: care Codec2Codec vs DPCM:BE
Current asoc_simple_init_for_codec2codec() adds default Codec2Codec
settings if rtd was Codec only.
But DPCM:BE also judged as Codec only, because dummy-DAI doesn't have
"endianness" (which is key parameter to judge as Codec).

This patch ignores setup Codec2Codec settings if it was DPCM:BE case.

ASoC: Refactor non_legacy_dai_naming flag
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Historically, the legacy DAI naming scheme was applied to platform
drivers and the newer scheme to CODEC drivers. During componentisation
the core lost the knowledge of if a driver was a CODEC or platform, they
were all now components. To continue to support the legacy naming on
older platform drivers a flag was added to the snd_soc_component_driver
structure, non_legacy_dai_naming, to indicate to use the new scheme and
this was applied to all CODECs as part of the migration.

However, a slight issue appears to be developing with respect to this
flag being opt in for the non-legacy scheme, which presumably we want to
be the primary scheme used. Many codec drivers appear to forget to
include this flag:

  grep -l -r "snd_soc_component_driver" sound/soc/codecs/*.c |
  xargs grep -L "non_legacy_dai_naming" | wc
     48      48    556

Whilst in many cases the configuration of the DAIs themselves will cause
the core to apply the new scheme anyway, it would seem more sensible to
change the flag to legacy_dai_naming making the new scheme opt out. This
patch series migrates across to such a scheme.

Specify clock provider directly to CPU DAIs
Merge series from Charles Keepax <ckeepax@opensource.cirrus.com>:

Currently the set_fmt callback always passes clock provider/consumer
with respect to the CODEC. This made sense when the framework was
directly broken down into platforms and CODECs. However, as things
are now broken down into components which can be connected as either
the CPU or CODEC side of a DAI link it simplifies things if each
side of the link is just told if it is provider or consumer of the
clocks. Making this change allows us to remove one of the last parts
of the ASoC core that needs to know if a driver is a CODEC driver,
where it flips the clock format specifier if a CODEC driver is used on
the CPU side of a DAI link, as well as just being conceptually more
consistent with componentisation.

The basic idea of this patch chain is to change the set_fmt callback
from specifying if the CODEC is provider/consumer into directly
specifying if the component is provider/consumer. To do this we add
some new defines, and then to preserve bisectability, the migration is
done by adding a new callback, converting over all existing CPU side
drivers, converting the core, and then finally reverting back to the
old callback.

Converting the platform drivers makes sense as the existing defines
are from the perspective of the CODEC and there are more CODEC drivers
than platform drivers.

Obviously a fair amount of this patch chain I was only able to build
test, so any testing that can be done would be greatly appreciated.

asoc_simple_init_dai_link_params() to initialize dai_link "params".
It is very straight naming, but difficult to noticed that it is for

on ALSA SoC, thus it is very important to clarify it. This patch
renames the function name.

ASoC: simple-card-utils: Move snd_soc_component_is_codec to be local
The helper function snd_soc_component_is_codec is based off the
presence of the non_legacy_dai_naming flag. This isn't super robust
as CPU side components may also specify this flag, and indeed the
kernel already contains a couple that do. After componentisation there
isn't really a totally robust solution to identifying what is a CODEC
driver, without introducing a flag specifically for that purpose, and
really the desirable direction to move in is that the distinction
doesn't matter.

This patch does two things to try to mitigate these problems. Firstly,
now that all the other users of the helper function have been removed,
it makes the helper function local to the driver rather, than being
part of the core. This should help to discourage any new code from
being created that depends on the CODEC driver distinction. Secondly,
it updates the helper function itself to use the endianness flag
rather than the non_legacy_dai_naming flag. The endianness flag is
definitely invalid on a CPU side component, so it a more reliable
indicator that the device is definitely a CODEC. The vast majority of
buses require the CODEC to set the endianness flag, so the number of
corner cases should be fairly minimal. It is worth noting that CODECs
sending audio over SPI, or built into the CPU CODECs are potential
corner cases, however the hope is that in most cases those types of
devices do not consitute a simple audio card.
