Changes in v2:
- Rebase on asoc/for-next
- New patch: "ASoC: Intel: bytct_rt5640: Add a separate "Headset Mic 2"
  DAPM pin for the mic on the 2nd jack"
- Addressed Pierre-Louis' comments about calling
  acpi_dev_add_driver_gpios() twice

Original cover-letter:

The HP Elitepad 1000 G2 tablet has 2 headset jacks:

1. on the dock which uses the output of the codecs built-in HP-amp +
the standard IN2 input which is always used with the headset-jack.

2. on the tablet itself, this uses the line-out of the codec + an external
HP-amp, which gets enabled by the ALC5642 codec's GPIO1 pin; and IN1 for
the headset-mic.

The codec's GPIO1 is also its only IRQ output pin, so this means that
the codec's IRQ cannot be used on this tablet. Instead the jack-detect
is connected directly to GPIOs on the main SoC. The dock has a helper
chip which also detects if a headset-mic is present or not, so there
are 2 GPIOs for the jack-detect status of the dock. The tablet jack
uses a single GPIO which indicates if a jack is present or not.

Differentiating between between headphones vs a headset on the tablet jack
is done by using the usual mic-bias over-current-detection mechanism.

Regards,

Hans

Thanks Hans, the code in patch6 looks much simpler now.

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
