Applied to https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next Thanks! [1/2] ASoC: dt-bindings: imx-card: Add binding doc for imx sound card commit: 623cd9cfcac522647e3624e48bf0661a39e8502a [2/2] ASoC: imx-card: Add imx-card machine driver commit: aa736700f42fa0813e286ca2f9274ffaa25163b9 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

Imx-card is a new added machine driver for supporting ak4458/ak5558/ak5552/ak4497 codec on i.MX platforms. But these DAC/ADCs are not only supported codecs. This machine driver is designed to be a more common machine driver for i.MX platform, it can support widely cpu dai interface and codec dai interface.
