[alsa-devel] [PATCH 1/3] ASoC: rt5682: improve the sensitivity of push button
From: Shuming Fan shumingf@realtek.com
The sensitivity could improve by decreasing the HW debounce time and reduce the delay time of workequeue. This patch added a device property for HW debounce time control. We could change this value to tune the sensitivity of push button.

and reduce the delay time of workequeue.
typo: work queue.
This patch added a device property for HW debounce time control. We could change this value to tune the sensitivity of push button.
so for an Intel platform without DT, could we set this property in the machine driver as done for bytcr_rt5640/51?

This should have a matching binding document update.
The patch
ASoC: rt5682: improve the sensitivity of push button
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 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
