[PATCH V2 1/4] ASoC: amd: ps: implement api to retrieve acp device config
Implement API to retrieve acp device config and calculate platform device count and dev mask for platform device node creation.
Currently for DMIC configuration, mask and dev count are calculated. Same api will be used to extend support for different ACP device configurations.

Refactor platform device creation implementation. Based on platform dev count and pdev mask create platform devices. Use common API to fill platform dev information. Use pdev count variable in remove callback for unregistering platform devices.

Instead of using hard coded index value for platform device index, retrieve the device index based on platform devices created. In PDM config case, ACP PCI driver retrieves dev index from pdm_dev_index variable. This will avoid overhead when multiple endpoint combinations support is added later. platform device index will vary based on audio endpoint configuration.

Move irq handler registration prior to platform device creation logic. This will avoid irq handling missing scenario when platform device raise interrrupts during it's probe sequence.

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
