[PATCH v2 0/3] ASoC: Intel: avs: Add support for sending initial module config
In some cases it may be desirable to provide default initial configuration for FW module using payload. To facilitate such solution extend topology to contain initial config information, parse it and then send data to FW if present.

Allow for defining initial config which will be send after module initialization to configure initial module state. This is only useful for modules which need to be configured on init.

If there are initial configs to send to module on init do send them.

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
