[alsa-devel] [PATCH 2/3] ASoC: dt-bindings: rt5682: add button delay device property

[shumingf]

From: Shuming Fan <shumingf@realtek.com>

The btndet-delay device property could control the HW debounce time.
It is easy to adjust the sensitivity of push button.

[alsa-devel] Applied "ASoC: dt-bindings: rt5682: add button delay device property" to the asoc tree

[Mark Brown]

The patch

   ASoC: dt-bindings: rt5682: add button delay device property

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.5

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
