ASoC: sunxi: do not select COMMON_CLK to fix builds
COMMON_CLK is a user-selectable option with its own dependencies.  The
most important dependency is !HAVE_LEGACY_CLK.  User-selectable drivers
should not select COMMON_CLK because they will create a dependency cycle
and build failures.  For example on MIPS a configuration with COMMON_CLK
(selected by SND_SUN8I_CODEC) and HAVE_LEGACY_CLK (selected by
SOC_RT305X) is possible:

ASoC: sun4i-i2s: Set sign extend sample
On the newer SoCs such as the H3 and A64 this is set by default
to transfer a 0 after each sample in each slot. However the A10
and A20 SoCs that this driver was developed on had a default
setting where it padded the audio gain with zeros.

This isn't a problem while we have only support for 16bit audio
but with larger sample resolution rates in the pipeline then SEXT
bits should be cleared so that they also pad at the LSB. Without
this the audio gets distorted.

Set sign extend sample for all the sunxi generations even if they
are not affected. This will keep consistency and avoid relying on
default.

We are actually using a complex formula to just return a bunch of

get_wss() the function return 4 instead of 3.

Replace this with a simpler switch case.

Also drop the i2s params which is unused and return a simple int as
returning an error code could be out of range for an s8 and there is
no optim to return a s8 here.

ASoC: sun4i-i2s: Change set_chan_cfg() params
As slots and slot_width can be set manually using set_tdm().
These values are then kept in sun4i_i2s struct.
So we need to check if these values are set or not.

This is not done actually and will trigger a bug.
For example, if we set to the simple soundcard in the device-tree
dai-tdm-slot-width = <32> and then start a stream using S16_LE,
currently we would calculate BCLK for 32-bit slots, but program
lrck_period for 16-bit slots, making the sample rate double what we
expected.

To fix this, we need to check if these values are set or not but as
this logic is already done by the caller. Avoid duplicating this
logic and just pass the required values as params to set_chan_cfg().

ASoC: sun8i-codec: Add the AIF3 DAI, widgets, and routes
AIF3 has some differences from AIF1 and AIF2:
 - It supports one channel only
 - It supports master mode only
 - It is not directly connected to any of the mixers; instead all audio
   goes through a mux with AIF2.
 - It does not have its own clock dividers; instead it reuses AIF2 BCLK
   and LRCK. This means that when both AIF2 and AIF3 are active, they
   must use the same sample rate and total frame width. Since AIF2 and
   AIF3 are only used for codec2codec DAI links, constraints are not
   applicable here; the only thing we can do when the rates don't match
   is report an error.

Make the necessary adjustments to support this AIF.

ASoC: sun8i-codec: Automatically set the system sample rate
The sun8i codec has three clock/sample rate domains:
 - The AIF1 domain, with a sample rate equal to AIF1 LRCK
 - The AIF2 domain, with a sample rate equal to AIF2 LRCK
 - The SYSCLK domain, containing the ADC, DAC, and effects (AGC/DRC),
   with a sample rate given by a divisor from SYSCLK. The divisor is
   controlled by the AIF1_FS or AIF2_FS field in SYS_SR_CTRL, depending
   on if SYSCLK's source is AIF1CLK or AIF2CLK, respectively. The exact
   sample rate depends on if SYSCLK is running at 22.6 MHz or 24.6 MHz.

When an AIF (currently only AIF1) is active, the ADC and DAC should run
at that sample rate to avoid artifacting. Sample rate conversion is only
available when multiple AIFs are active and are routed to each other;
this means the sample rate conversion hardware usually cannot be used.

Only attach the event hook to the channel 0 AIF widgets, since we only
need one event when a DAI stream starts or stops. Channel 0 is always
brought up with a DAI stream, regardless of the number of channels in
the stream.

The ADC and DAC (along with their effects blocks) can be used even if
no AIFs are in use. In that case, we should select an appropriate sample
rate divisor, instead of keeping the last-used AIF sample rate.
44.1/48 kHz was chosen to balance audio quality and power consumption.

Since the sample rate is tied to active AIF paths, disabling pmdown_time
allows switching to the optimal sample rate immediately, instead of
after a 5 second delay.

ASoC: sun8i-codec: Enable AIF mono/stereo control
Each left/right pair of AIF input/output channels can be swapped or

of a stereo sink, or for creating complex mixing scenarios.

Add the support to control this feature from userspace.

ASoC: sun8i-codec: Correct DAPM widget types
Whie the aif_in and aif_out widget types are handled exactly the same in
the core DAPM code, a future widget event hook will need the correct
widget type to derive the associated substream. Clean up the widget type
for that reason, and so these widgets will match newly-added widgets for
the other AIFs.

ASoC: sun8i-codec: Consistently name DAPM widgets and routes
This cleans up the mixer widget names. The AIF1 AD0 Mixer names were
previously wrong -- they do not control the digital side of the ADC. The
DAC mixer widgets were not wrong, but they were verbose and did not
match the naming scheme of the other widgets.

The mixer controls are not renamed because they are exposed to

ASoC: sun8i-codec: Sort DAPM controls, widgets, and routes
Sort the remaining pieces of the DAPM driver so that they are all in the
same order among controls/widgets/routes, and so they roughly match the
register word and bit order of the hardware. This nicely separates the
AIF-related widgets from the ADC/DAC widgets, which allows the AIF
widgets to stay in a logical order as more AIFs are added to the driver.

No widgets are renamed, to ease verification that this commit makes no
functional change.

ASoC: sun8i-codec: Swap module clock/reset dependencies
This matches the module power-up/down sequence from the vendor's driver.

While updating these widgets/routes, reorder them to match the register
and bit layout of the hardware. This puts them in the same place in the
widget and route arrays (previously they were at opposite ends), and it
makes it easier to track which parts of which registers are implemented.

ASoC: sun8i-codec: Set up clock tree at probe time
The sun8i codec is effectively an on-die variant of the X-Powers AC100
codec. The AC100 can derive its clocks from either of two I2S master
clocks or an internal PLL. For the on-die variant, Allwinner replaced
the codec's own PLL with a connection to SoC's existing PLL_AUDIO, and
they connected both I2S MCLK inputs to the same source -- which happens
to be an integer divider from the same PLL_AUDIO.

So there's actually no clocking flexibility. To run SYSCLK at the
required rate, it must be run straight from the PLL. The only choice is
whether it goes through AIF1CLK or AIF2CLK. Since both run at the same
rate, the only effect of that choice is which field in SYS_SR_CTRL
(AIF1_FS or AIF2_FS) controls the system sample rate.

Since AIFnCLK is required to bring up the corresponding DAI, and AIF1
(connected to the CPU) is used most often, let's use AIF1CLK as the
SYSCLK parent. That means we no longer need to set AIF2_FS.

Since this clock tree never changes, we can program it from the
component probe function, instead of using DAPM widgets. The DAPM
widgets unnecessarily change clock parents when the codec goes in/out
of idle and the supply widgets are powered up/down.

Merge series "Allwinner A64 digital audio codec fixes" from Samuel Holland <samuel@sholland.org>:
This series fixes a couple of issues with the digital audio codec in the
Allwinner A64 SoC:
  1) Left/right channels were swapped when playing/recording audio
  2) DAPM topology was wrong, breaking some kcontrols

This is the minimum set of changes necessary to fix these issues in a
backward-compatible way. For that reason, some DAPM widgets still have
incorrect or confusing names; those and other issues will be fixed in
later patch sets.
