When compiled with CONFIG_HAVE_CLK, the kernel need to get provider for the
clock API. This is usually selected by the platform and the sound drivers
should not really care about this. However COMPILE_TEST is special and the
platform required may not have been selected, leading to this type of
error:
> aiu-encoder-spdif.c:(.text+0x3a0): undefined reference to `clk_set_parent'
Since we need a sane provider of the API with COMPILE_TEST, depends on
COMMON_CLK.

On g12 and following platforms, The first channel of record with more than
2 channels ends being placed randomly on an even channel of the output.
On these SoCs, a bit was added to force the first channel to be placed at
the beginning of the output. Apparently the behavior if the bit is not set
is not easily predictable. According to the documentation, this bit is not
present on the axg series.
Set the bit on g12 and fix the problem.

Commit b73287f0b0 ("ASoC: soc-pcm: dpcm: fix playback/capture checks")
changed the meaning of dpcm_playback/dpcm_capture and now requires the
CPU DAI BE to aligned with those flags.
This broke all Amlogic cards with uni-directional backends (All gx and
most axg cards).
While I'm still confused as to how this change is an improvement, those
cards can't remain broken forever. Hopefully, next time an API change is
done like that, all the users will be updated as part of the change, and
not left to fend for themselves.

After carefully checking, it appears that both tdmout and tdmin require the
rising edge of the sclk they get to be synchronized with the frame sync
event (which should be a rising edge of lrclk).
TDMIN was improperly set before this patch. Remove the sclk_invert quirk
which is no longer needed and fix the sclk phase.

snd_soc_dai_digital_mute() is internally using both
mute_stream() (1) or digital_mute() (2), but the difference between
these 2 are only handling direction.
We can merge digital_mute() into mute_stream
int snd_soc_dai_digital_mute(xxx, int direction)
{
...
else if (dai->driver->ops->mute_stream)
(1) return dai->driver->ops->mute_stream(xxx, direction);
else if (direction == SNDRV_PCM_STREAM_PLAYBACK &&
dai->driver->ops->digital_mute)
(2) return dai->driver->ops->digital_mute(xxx);

We had read/write function for Codec, Platform, etc,
but these has been merged into snd_soc_component_read/write().
Internally, it is using regmap or driver function.
In read case, each styles are like below
regmap
ret = regmap_read(..., reg, &val);
driver function
val = xxx->read(..., reg);
Because of this kind of different style, to keep same read style,
when we merged each read function into snd_soc_component_read(),
we created snd_soc_component_read32(), like below.
commit 738b49efe6 ("ASoC: add snd_soc_component_read32")
(1) val = snd_soc_component_read32(component, reg);
(2) ret = snd_soc_component_read(component, reg, &val);
Many drivers are using snd_soc_component_read32(), and
some drivers are using snd_soc_component_read() today.
In generally, we don't check read function successes,
because, we will have many other issues at initial timing
if read function didn't work.
Now we can use soc_component_err() when error case.
This means, it is easy to notice if error occurred.
This patch aggressively merge snd_soc_component_read() and _read32(),
and makes snd_soc_component_read/write() as generally style.
This patch do
1) merge snd_soc_component_read() and snd_soc_component_read32()
2) it uses soc_component_err() when error case (easy to notice)
3) keeps read32 for now by #define
4) update snd_soc_component_read() for all drivers
Because _read() user drivers are not too many, this patch changes
all user drivers.

While this error was initially reported the axg-card type, it also applies
to the gx-card type.
While initiliazing the links, ASoC treats the codec-to-codec links of this
card type as a DPCM backend. This error eventually leads to the Oops.
Most of the card driver code is shared between DPCM backends and
codec-to-codec links. The property "no_pcm" marking DCPM BE was left set on
codec-to-codec links, leading to this problem. This commit fixes that.

The AIU audio controller on the Meson8 and Meson8b SoC families is
compatible with the one found in the later GXBB family. Add compatible
strings for these two older SoC families so the driver can be loaded for
them.
Instead of using the I2S divider from the AIU_CLK_CTRL_MORE register we
need to use the I2S divider from the AIU_CLK_CTRL register. This older
register is less flexible because it only supports four divider settings
(1, 2, 4, 8) compared to the AIU_CLK_CTRL_MORE register (which supports
dividers in the range 0..64).

Introduce a struct aiu_platform_data to make the driver aware of
platform specific information. Convert the existing check for the
internal stereo audio codec (only available on GXL) to this new struct.
Support for the 32-bit SoCs will need this as well because the
AIU_CLK_CTRL_MORE register doesn't have the I2S divider bits (and we
need to use the I2S divider from AIU_CLK_CTRL instead).

The aiu stored the irq in an unsigned integer which may have discarded an
error returned by platform_get_irq_byname(). This is incorrect and should
have been a signed integer.
Also drop the irq error traces from the probe function as this is already
done by platform_get_irq_byname().
