This patchset adds support to WSA8810/WSA8815 Class-D Smart Speaker
Amplifier which is SoundWire interfaced.
This patchset along with DB845c machine driver and WCD934x codec driver
has been tested on SDM845 SoC based DragonBoard DB845c with two
WSA8810 and Lenovo YOGA C630 Laptop based on SDM850 with WSA8815
speaker amplifiers.
Most of the code in this driver is rework of Qualcomm downstream drivers
used in Andriod. Credits to Banajit Goswami and Patrick Lai's Team.
TODO:
Add thermal sensor support in WSA881x.
Thanks,
srini
Changes since v10:
- Add check in hw_free for prepare status

This patch adds bindings for WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier also has a simple thermal sensor for
over temperature and speaker protection.

This patch adds support to WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier is primarily interfaced with SoundWire.
One WSA is used for mono speaker configuration and second one
would give stereo setup.
This patch is tested on SDM845 based DragonBoard DB845c and
Lenovo YOGA C630 Laptop based on SDM850 with WSA8815
speaker amplifiers.

The patch
ASoC: codecs: add wsa881x amplifier support
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6
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

Subject: [PATCH] ASoC: codecs: add wsa881x amplifier support
This patch adds support to WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier is primarily interfaced with SoundWire.
One WSA is used for mono speaker configuration and second one
would give stereo setup.
This patch is tested on SDM845 based DragonBoard DB845c and
Lenovo YOGA C630 Laptop based on SDM850 with WSA8815
speaker amplifiers.

The patch
dt-bindings: ASoC: Add WSA881x bindings
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.6
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

Subject: [PATCH] dt-bindings: ASoC: Add WSA881x bindings
This patch adds bindings for WSA8810/WSA8815 Class-D Smart Speaker
Amplifier. This Amplifier also has a simple thermal sensor for
over temperature and speaker protection.

This schema now is applied to the soundwire-controller.yaml example and fails:
Documentation/devicetree/bindings/soundwire/soundwire-controller.example.dt.yaml:
speaker@0,1: '#sound-dai-cells' is a required property
Documentation/devicetree/bindings/soundwire/soundwire-controller.example.dt.yaml:
speaker@0,2: '#sound-dai-cells' is a required property
Please fix.
