Subject: [PATCH 4/6] ASoC: mediatek: add MT7622 AFE support

This patch adds support for the MT7622 AFE which reuses MT2701 driver.

We also introduce the 'struct mt2701_soc_variants' to differentiate
between the SoC generations as there might be other (existing or future)
chips that use the same binding and driver, then being a little more
abstract could help in the long run.

Subject: Applied "ASoC: mediatek: use snd_soc_dai_get_drvdata() to get the private data" to the asoc tree

The patch

ASoC: mediatek: use snd_soc_dai_get_drvdata() to get the private data

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

Subject: Applied "ASoC: mediatek: use snd_soc_dai_get_drvdata() to get the private data" to the asoc tree

The patch

ASoC: mediatek: use snd_soc_dai_get_drvdata() to get the private data

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

Subject: Applied "ASoC: mediatek: Add MTK_STREAM_NUM to mtk-base-afe.h" to the asoc tree

The patch

ASoC: mediatek: Add MTK_STREAM_NUM to mtk-base-afe.h

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

Subject: [PATCH] ASoC: mediatek: Add MTK_STREAM_NUM to mtk-base-afe.h

Add MTK_STREAM_NUM to common header and modify related stuff so that
the other SoCs can reuse it.

Subject: Applied "ASoC: mediatek: simplify the control logic of MT2701 I2S" to the asoc tree

The patch

ASoC: mediatek: simplify the control logic of MT2701 I2S

has been applied to the asoc tree at

https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

the next merge window (or sooner if it is a bug fix), however if

You may get further e-mails resulting from automated or manual testing

Subject: [PATCH] ASoC: mediatek: add MT7622 AFE support

This patch adds support for the MT7622 AFE which reuses MT2701 driver.

We also introduce the 'struct mt2701_soc_variants' to differentiate
between the SoC generations as there might be other (existing or future)
chips that use the same binding and driver, then being a little more
abstract could help in the long run.
