Add support for TI TAS6424 digital amplifier

Hello all,

This series adds support for the TAS6424 digital amplifier. A lot has changed from the last time this upstreaming was attempted, I've taken over this effort for Michael and I don't really have an exact change log but hopefully I've addressed all comments from v3.

Thanks,
Andrew

Please use subject lines matching the style for the subsystem. This makes it easier for people to identify relevant patches.

The patch

ASoC: tas6424: add bindings for TAS6424

has been applied to the asoc tree at

https://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

From: Andreas Dannenberg <[email protected]>

The Texas Instruments TAS6424 device is a high-efficiency quad-channel Class-D audio power amplifier. Its digital time division multiplexed (TDM) interface enables up to 2 devices to share the same bus, supporting a total of eight channels from one audio serial port.
