The patch ASoC: SOF: Intel: hda: Enable jack detection has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-5.4 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 fd15f2f5e272145269bcbf834e0e0b560a575891 Mon Sep 17 00:00:00 2001 From: Rander Wang <rander.wang@xxxxxxxxxxxxxxx> Date: Mon, 22 Jul 2019 09:13:53 -0500 Subject: [PATCH] ASoC: SOF: Intel: hda: Enable jack detection In commit 7d4f606c50ff ("ALSA: hda - WAKEEN feature enabling for runtime pm"), legacy HD-A driver sets hda controller in reset mode after entering runtime-suspend. And when resuming from suspend mode, it checks hda controller & codec status to detect headphone hotplug event. Now this patch does the same job in SOF runtime pm functions. And we need to check all the non-hdmi codecs for some cases like playback with HDMI or capture with DMIC connected to dsp. In these cases, only controller is active and codecs are suspended, so codecs can't send unsolicited event to controller. The jack polling operation will activate codecs and unsolicited event can work even codecs become suspended later. Tested on whiskylake with hda codecs.
