[alsa-devel] [PATCH 0/4] ASoC: SOF: i.MX8 SAI and Intel ALH/SoundWire DAI support
This patchset adds the basic functionality to extract DAI information from the topology and send the information to firmware.
The i.MX8 SAI/ESAI definitions are minimal placeholders for now, they are included to keep the alignment with the firmware/topology.
For the Intel ALH, there is no specific configuration in topology file, all the programming takes place based on the dai index and the related ALH stream ID. The renaming from SoundWire to ALH (Audio Link Hub) is a better representation of the hardware, the ALH acts as a proxy between the DMA transfers and the Cadence IP.

The patch
ASoC: SOF: topology: Add dummy support for i.MX8 DAIs
has been applied to the asoc tree at
https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4
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.
