[PATCH 0/2] sc7180: Add qdsp baked soundcard
Some devices, such as Acer Aspire 1, can't use lpass dirrectly, but instead must use adsp core to play sound. Since otherwise the hardware is, usually, very similar across the devices on the same platform, it makes sense to reuse the same boardfile. This series refactors the sc7180.c slightly and adds the functions to control clocks via adsp instead of controlling the hardware directly. Existing google devices should experience no change.

Some sc7180 devices use audio adsp to play sound. The setup for this adsp is similar to the dirrect lpass usage but requires the use of different link ids and clocks. This commit adds support for the qdsp based audio, reusing the common parts like audio codec setup and jack creation. Since the setup is mostly generic and codec specific setup is guarded behind a check, a generic compatible is added, similar to other platforms. Even though those changes target Acer Aspire 1 as the only user of the adsp audio on this platform present upstream at the moment of the commit, those changes should be either dirrectly compatible or trivially expandable to the other devices that will be added in the future.

At least I was consistent in failing to pick the correct word... If we get to v2, I will try to remember about those, but if not, I guess I will accept the chance, that in a couple of years I may wake up in cold sweat upon realizing that this mistake is forever immortalized in the Linux git history... Thanks for noticing this! Nikita

Some devices, such as Acer Aspire 1, can't use lpass dirrectly, but instead must use adsp core to play sound. Since otherwise the hardware is, usually, very similar across the devices on the same platform, it makes sense to reuse the same boardfile.
This series refactors the sc7180.c slightly and adds the functions to control clocks via adsp instead of controlling the hardware directly.

Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/2] ASoC: dt-bindings: qcom,sm8250: Add sc7180-qdsp6-sndcard commit: 5443d186163c6ab0084a5b23c901e0f9ba792463 [2/2] ASoC: qcom: sc7180: Add support for qdsp6 baked sound commit: 4531f512e3ef147f07d47bceb256c0af5ab130b7 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
