[PATCH 0/7] Add support for cs42l45 into the Intel machine driver

[Charles Keepax]

Now that the full class driver is in place we can add support to the
Intel machine driver for Cirrus's new SDCA audio CODEC the cs42l45. This
makes some minor tweaks to the machine driver itself to support SDCA
devices, and then adds the necessary tables etc. to define the device.

Note, this series shouldn't have any dependencies on the other series of
improvements to the class driver that is already on the list. So either
can be merged first.

Thanks,
Charles

[PATCH 1/7] ASoC: SDCA: Align mute controls to ALSA expectations

[Charles Keepax]

Currently mute controls will be called "FU xx Mute Switch" (note
the switch is added programmatically outside the coverage of this
patch) and the accompanying volume control would be called "FU xx
Channel Volume".  These names are taken from the SDCA specification,
however, this does not mesh well with the ALSA naming system. ALSA
generally expects enables rather than mutes and expects that mutes
and volumes have matching names.

Update the names and invert the mute controls to make them more
standard "FU XX Channel Switch", this does slightly deviate from
the SDCA specification but it makes the rest of the Linux ecosystem
a lot happier.

And there was me thinking you were going to address the FU bit. :)

Lol, yes it's a spectacular choice isn't it, I mean it just

[PATCH 2/7] ASoC: SDCA: Add terminal type into input/output widget name

[Charles Keepax]

There have been some complaints around the UCM files for SDCA
devices that the control system is quite hard to follow. This is
definitely true without the specification handy the naming can be
a little cryptic. However, as most of the information is parsed
from DisCo there are some limits to what the driver can safely do
to improve this.

However, one area that can be improved is the non-streaming
input/output terminals. These have a field (enum sdca_terminal_type)
that describes the usage of that terminal. These types can be
appended to the entity name to give the users a better clue as
to the purpose. For example "OT 43", would now become "OT 43
Headphone". This would follow through into the jack controls which
would change from "OT 43 Jack" to "OT 43 Headphone Jack", making the
purpose much more obvious to the user.

This provides slightly more readable controls without relying on
implicit knowledge that individual parts might not conform to.

[PATCH 3/7] ASoC: sdw_utils: Add codec_conf for every DAI

[Charles Keepax]

The assumption so far is that all the DAI links for a given audio part
would be on the same device. However, as SDCA implements each audio
function on a separate auxiliary driver this will no longer be true.
This means it is necessary to add additional codec_conf structures to
get the prefix for an audio part to apply to all the auxiliary drivers
that make up that part.

[PATCH 4/7] ASoC: sdw_utils: Move codec_name to dai info

[Charles Keepax]

As SDCA devices will support each DAI link on a different child device,
move the codec name from codec_info to each dai_info. To allow the
appropriate function device to be bound to each DAI link.

[PATCH 5/7] ASoC: intel: sof_sdw: Add ability to have auxiliary devices

[Charles Keepax]

Currently the sof_sdw machine driver assumes that all devices involved
in the sound card are connected through a DAI link. However for SDCA
devices we still want the HID (Human Interface Device, used for jack
buttons) to be part of the sound card, but it contains no DAI links.

Add support into the machine driver to specify a list of auxiliary
devices to merged into the card.

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
