Applied "ASoC: rt5645: Modify the headphone depop and calibration function to prevent the pop sound in the booting time" to the asoc tree

[Mark Brown]

The patch

   ASoC: rt5645: Modify the headphone depop and calibration function to prevent the pop sound in the booting time

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

[Mark Brown]

The patch

   ASoC: rt5645: Modify the jack detection function to prevent the pop sound while the jack plug in

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

Yay, magic numbers!  What is the issue this is fixing?  The core is
supposed to power everything down to _BIAS_OFF before exiting, are we
missing something here?

It de-initialed our jack detection function, and it cannot be turned off in
_BIAS_OFF. If we didn't de-initial it, we will hear the pop sound in the
situation of powering off, thanks.

OK, can you add a comment explaining what the register writes do (or
ideally move to using #defines for the register values so it's obvious
just from looking at the writes)?
