The patch ASoC: es8316: Add support for inverted jack detect has been applied to the asoc tree at https://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 >From 0bbcedd6bb41b82b77115fc001441ff34e7c4ea7 Mon Sep 17 00:00:00 2001 From: Paul Cercueil <paul@xxxxxxxxxxxxxxx> Date: Fri, 29 Mar 2019 22:50:43 +0100 Subject: [PATCH] ASoC: es8316: Add support for inverted jack detect On some devices (Teclast X98+ II tablet, maybe others), the jack detection has been wired backwards, so when the ES8316 reports headphones being present it means they are actually not plugged. Use a quirk around this incorrect behaviour, which can be enabled through the 'everest,jack-detect-inverted' boolean device property.
