[PATCH v3 0/2] Add codec machine driver for rockchip platform

[PATCH v3 0/2] Add codec machine driver for rockchip platform

[Xing Zheng]

From: zhengxing <zhengxing@rock-chips.com>


Hi,
  The simple-card is not common at present, soc maybe need own machine
driver for jack detection.
  Add drivers for two families of rockchip-bases chromebooks. These
machine drives don't use simplecard because we need custom jack
detection plumbing.

- use ts3a227e for ext jack detection with max98090
- call rt5645_set_jack_detect function via rt5645 codec driver

Thanks.

Applied "ASoC: rockchip: Add machine driver for rt5645/rt5650 codec" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip: Add machine driver for rt5645/rt5650 codec

has been applied to the asoc tree at

   git://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

Applied "ASoC: rockchip: Add machine driver for max98090 codec" to the asoc tree

[Mark Brown]

The patch

   ASoC: rockchip: Add machine driver for max98090 codec

has been applied to the asoc tree at

   git://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
