[PATCH v4 0/2] Add power domains support for digital macro codecs
This patch set is to add power domains support for RX, TX and VA macros.
Changes since v3: -- Add dt-bindings support. Changes since v2: -- Remove redundant local variable. -- Update pds error handling sequence. -- Update module description. -- Clean up pds init function. -- Remove redundant arguments. Changes since v1: -- Add missing macros in Kconfig.

Add support for enabling required power domains in digital macro codecs. macro and dcodec power domains are being requested as clocks by HLOS in ADSP based architectures and ADSP internally handling as powerdomains. In ADSP bypass case need to handle them as power domains explicitly.

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
