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.

The AIF clock control register has the same layout for all three AIFs.
The only difference between them is that AIF3 is missing some fields. We
can reuse the same register field definitions for all three registers,
and use the DAI ID to select the correct register address.

Now that the DAI clock setup is correct for all hardware-supported PCM
formats, we can enable them in the driver. With the appropriate support
in the CPU DAI driver, this allows userspace to access the additional
formats.
Since this codec is connected to the CPU via a DAI, not directly, we do
not care if the CPU DAI is using 3-byte or 4-byte formats, so we can
support them both.

Now that we guarantee that SYSCLK is running at the optimal rate when

SYSCLK will always be an integer multiple of BCLK. So we can always

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.

The system sample rate programmed into the hardware is really a clock
divider from SYSCLK to the ADC and DAC. Since we support two SYSCLK
frequencies, we can use all sample rates corresponding to one of those
frequencies divided by any available divisor.
This commit enables support for those sample rates. It also stops
advertising support for a 64 kHz sample rate, which is not supported.

The AIFs have a single register controlling DAI parameters in both
directions, including BCLK/LRCK divisor and word size. The DAIs produce
only noise or silence if any of these parameters is wrong. Therefore, we
need to enforce symmetry for these parameters, so starting a new
substream will not break an existing substream.

Previously, the BCLK divisor calculation assumed zero padding and
exactly two slots. In order to support the TDM slot binding and
20/24-bit word sizes, those assumptions must be removed.
Due to hardware limitations, the BCLK/LRCK ratio is not as simple as
"slot_width * slots". However, the correct value is already calculated
elsewhere in this function, since it must also be programmed into the
hardware. Reuse that value to calculate the correct SYSCLK/BCLK divisor.

The codec supports only power-of-two BCLK/LRCK divisors. If either the
slot width or the number of slots is not a power of two, the LRCK
divisor must be rounded up to provide enough space. To do that, use
order_base_2 (instead of ilog2, which rounds down).
Since the rounded divisor is also needed for setting the SYSCLK/BCLK
divisor, return the order base 2 instead of fully calculating the
hardware register encoding.

The LRCK inversion bit has a different meaning in DSP mode: it selects

In preparation for adding additional DAIs to this component, convert the
DAI driver definition to an array. Since this changes all of the lines
in the definition anyway, let's move it closer to the ops function
definitions, instead of on the far side of the DAPM arrays. And while
moving the DAI driver ops, rename the set_fmt hook to match the usual
naming scheme.
Give the existing DAI an explicit ID and more meaningful stream names,
so it will remain unique as more DAIs are added. The AIF widget streams
must be updated to match.

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

This matches the module power-up/down sequence from the vendor's driver.
While updating these widgets/routes, reorder them to match the register

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.

The sun8i-codec driver provides ALSA controls for enabling/disabling
each of the inputs to the AIF1 Slot 0 and DAC mixers. For two of these
inputs (ADC->DAC and AIF1 DA0->AIF1 AD0), the audio source is
implemented, so the mixer inputs can be used.
However, because the DAPM routes are missing, these mixer inputs only
work when both the source and the mixer happen to be part of other
active audio paths. Adding the appropriate routes makes these ALSA
controls function all of the time.

The A33/A64 digital codec has 4 physical inputs and 4 physical outputs:
3 AIFs/DAIs and one ADC/DAC pair. Internal routing is accomplished by
a 4-channel mixer connected to each output.
The analog and digital sides of the ADC/DAC are in separate ASoC
components, so card-level DAPM routes (provided in the device tree) are
necessary to connect them together. Currently, these routes are wrong.
For AIF1 Playback, the correct topology is:
||<<============ sun8i-codec ===========>>||
|| ||
CPU DAI -> AIF1 DA0 -> DAC Mixer -> DAC (digital) -> DAC (analog)
|| ||
but the driver and device trees currently describe:
|| ||
CPU DAI -> AIF1 DA0 -------------------------------> DAC (analog)
|| \--> DAC Mixer -> ??? [dead end] ||
For AIF1 Capture, there is an additional problem, because the Mixer
route is backward. The topology should be:
|| ||
ADC (analog) -> ADC (digital) -> AIF1 AD0 Mixer -> AIF1 AD0 -> CPU DAI
|| ||
but the driver and device trees currently describe:
|| ||
ADC (analog) -> AIF1 AD0 ------------------------------------> CPU DAI
|| \--> ADC Mixer -> ??? [dead end] ||
The ADC/DAC are only powered because AIF1 AD0 (capture) has supply
routes from the ADC, and AIF1 DA0 (playback) has supply routes from the
DAC. However, neither set of supply routes matches the hardware
topology. Audio can be routed among AIF1/2/3 without using the ADC or
DAC at all; and audio can be routed from the ADC to the DAC without
using any AIFs (via the "ADC Digital DAC Playback Switch"). Because the
DAPM routes are wrong, both of these use cases are currently broken.
This commit adds the necessary widgets and routes to represent the real
hardware topology, with functionality equivalent to the current driver.
For the existing "allwinner,sun8i-a33-codec" compatible, widgets with
the old names are kept as wrappers around the new widgets, so existing
device trees will continue to work. For "allwinner,sun50i-a64-codec",
the old widgets can be omitted, because no device trees yet use that
compatible.

Use the correct mask for this two-bit field. This fixes setting the DAI
data format to RIGHT_J or DSP_A.

sun8i-codec misses a route from ADC to AIF1 Slot 0 ADC. Add it
to the driver to avoid adding it to every dts.

drvdata is actually sun8i_codec, not snd_soc_card, so it crashes
when calling snd_soc_card_get_drvdata().
Drop card and scodec vars anyway since we don't need to
disable/unprepare clocks - it's already done by calling
runtime_suspend()
Drop clk_disable_unprepare() calls for the same reason.

BCLK / LRCK ratio should be sample size * channels, but it was
hardcoded to 32 (0x1 is 32 as per A33 and A64 datasheets).
Calculate it basing on sample size and number of channels.

Now we can replace Codec to Component. Let's do it.
Note:
xxx_codec_xxx() -> xxx_component_xxx()
.idle_bias_off = 0 -> .idle_bias_on = 1
.ignore_pmdown_time = 0 -> .use_pmdown_time = 1
- -> .endianness = 1
- -> .non_legacy_dai_naming = 1

Add ADC support for the sun8i-codec driver.
This driver uses microphones widgets and routes provided by the
analog part (sun8i-codec-analog).
Some digital configurations are needed by creating new ADC widgets
and routes.
