[PATCH 0/7] Allwinner A64 digital audio codec fixes

[Samuel Holland]

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.

[PATCH 1/7] ASoC: dt-bindings: Add a new compatible for the A64 codec

[Samuel Holland]

The audio codecs in the A33 and A64 are both integrated variants of the
X-Powers AC100 codec. However, there are some differences between them
that merit having a separate compatible:
 - The A64 has a second DRC block, not present in the AC100 or A33.
 - The A33 has some extra muxing options for AIF1/2/3 in the
   AIF3_SGP_CTRL register, which are not present in the AC100 or A64.
 - The A33 is missing registers providing jack detection functionality.
 - The A33 is claimed to invert LRCK, but this is not seen on A64.

Since the driver will continue to work on the A64 using the A33
compatible, albeit without jack detection functionality and with
possibly inverted channels, as it does now, allow the A33 compatible
to be used as a fallback.

[PATCH 2/7] ASoC: sun8i-codec: Fix DAPM to match the hardware topology

[Samuel Holland]

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.

[PATCH 3/7] ASoC: sun8i-codec: Add missing mixer routes

[Samuel Holland]

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.

[PATCH 4/7] ASoC: sun8i-codec: Add a quirk for LRCK inversion

[Samuel Holland]

On the A64, as tested using the PinePhone, the current code causes the
left/right channels to be swapped during I2S playback from the CPU on
AIF1, and breaks DSP_A communication with the modem on AIF2. Both of
these are fixed when LRCK is no longer inverted.

Trusting that the comment in the code is correct, the existing behavior
is kept for the A33.

[PATCH 6/7] arm64: dts: allwinner: a64: Update codec widget names

[Samuel Holland]

The sun8i-codec driver introduced a new set of DAPM widgets that more
accurately describe the hardware topology. Update the various device
trees to use the new widget names.

[PATCH 7/7] arm64: dts: allwinner: a64: Update the audio codec compatible

[Samuel Holland]

The audio codec in the A64 has some differences from the A33 codec, so
it needs its own compatible. Since the two codecs are similar, the A33
codec compatible is kept as a fallback.

Using the correct compatible fixes a channel inversion issue and cleans
up some DAPM widgets that are no longer used.

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Ideally we should get the DT patches through arm-soc, can you drop the
patches 5 to 7?

Thanks!

When it says "no commit info" that means the patch wasn't applied.
