To support double channel shared controls split across 2 registers, one
for each channel, we must be able to update both registers together.
Add a second set of register fields to struct snd_soc_dapm_update, and
update the DAPM control writeback (put) callbacks to support this.
For codecs that use custom events which call into DAPM to do updates,
also clear struct snd_soc_dapm_update before using it, so the second
set of fields remains clean.

While DAPM is mono or single channel, its controls can be shared between
widgets, such as sharing one stereo mixer control between the left and
right channel widgets.
This patch introduces support for such shared mixer controls.

Based on this changelog I'm really not sure what the intended semantic
of this change is which makes it difficult to review. What are you
expecting these controls to look like and how are you expecting them to
work?

It looks like the goal is to attach more than one path to a single
control somehow?

Correct. I'll try to expand the commit log and add an example diagram.

This really only works for two channels with the current inteface - the
comment makes it sound like it'll work for more but we can only pass in
two (and there's only support for specifying two everywhere).

That seems like a bit of an assumption in cases where we've got a single
control for both power and volume? They're very rare though, I'm not
even sure any exist. It'd be good to have a check in the code just in
case it does come up, it'll likely be a nightmare to debug if someone
does run into it.
Otherwise I think this makes sense.

I could rework it to pass a list of connected status' and the number
of elements instead, but it wouldn't work well for situations where
the number of channels on the kcontrol != the number of paths. I'm not
sure if that's even a valid setup, but it does work with the current
core code.
On the other hand, are there kcontrols that are multi-channel
(> 2 channels)?
I'm inclined to just fixup the comment to make it clear that the
implementation supports stereo, i.e. 2 channels, only.

Agreed. I'll put a check and warning before it.

A DAPM_DOUBLE control type can be used for dual channel mixer input
selectors / mute controls in one register, possibly toggling both
channels together.
The control is meant to be shared by 2 widgets, 1 for each channel,
such that the mixer control exposed to userspace remains a combined
stereo control.

The patch
ASoC: dapm: Introduce DAPM_DOUBLE dual channel control type
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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.

The A31 has a similar codec to the A10/A20. The PCM parts are very
similar, with just different register offsets. The analog paths are
very different. There are more inputs and outputs.
The quirks structure is expanded to include different register offsets
and separate callbacks for creating the ASoC card. Also the DMA burst
length is increased to 8. While the A10 DMA engine supports bursts of
1, 4 and 8, the A31 engine only supports 1 and 8.
This patch adds support for the basic playback path of the A31 codec,
from the DAC to the headphones. Headphone detection, microphone,
signaling, other inputs/outputs and capture will be added later.

It's not completely unrelated. I want different create_card
functions for the different SoCs, and that has to be part of the
quirks, so the quirks and the of_match list have to be moved
below them. I suppose I could leave the regmap parts in place,
but keeping them together is nicer.
If I split out the addition of the .create_card field and
code movement into a separate patch, would that be OK?

only the one that change, so judging from your structure, only the ADC
fifo control, status and data registers.

Yep, that would work.

The A31 integrated codec has a stereo "Line In" input. Add support for
it to the playback paths.

The patch
ASoC: sun4i-codec: Add support for A31 Line In playback
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

The A31 integrated codec has a second "Line Out" output which does not
include an integrated amplifier in its path. This path does have a
separate volume control.
This patch adds support for the playback path from the DAC to the Line
Out pins.

The A31 internal codec has 3 microphone outputs, of which MIC2 and MIC3
are muxed internally. The resulting two microphone inputs have separate
gain controls and mixer inputs.
The codec also has 2 microphone bias pins. HBIAS is specifically for the
headphone jack, which also supports headphone detection and control
buttons. These extra functions are not supported yet. The other, MBIAS,
is for all other analog microphones.
There is also mention of digital microphone support, but documentation
is scarce, and no hardware with it is available.

The A31's internal codec capture path has a mixer in front of the ADC
for each channel, capable of selecting various inputs, including
microphones, line in, phone in, and the main output mixer.
This patch adds the various controls, widgets and routes needed for
audio capture from the already supported inputs on the A31.

The patch
ASoC: sun4i-codec: Add support for A31 ADC capture path
has been applied to the asoc tree at
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git
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

The A31 SoC's codec has various inputs, outputs and microphone bias
supplies. These can be routed on the board in different ways, such as:
- Microphones all use the MBIAS main microphone supply or one mic may
use the HBIAS supply, which supports headset detection and buttons.
- Line Out may be routed to an audio jack, or an onboard speaker amp
with power controls.
Add support for specifying the audio routes in the device tree.

The Hummingbird A31 has headset and line in audio jacks and an onboard
mic routed to the pins for the SoC's internal codec. The line out pins
are routed to an onboard speaker amp, whose output is available on a
pin header.
