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 e5b94083d0996b4c69674c8a5563c2eb272557ba Mon Sep 17 00:00:00 2001 From: "Fang, Yang A" Date: Fri, 7 Aug 2015 14:08:15 -0700 Subject: [PATCH] ASoC: max98090: Fix sequencing when starting additional routes Enforce correct device sequencing when configuring a new audio route when there is an existing active audio route(s). This patch fixed recording noise issue while playback is active. We have some registers which require the device to be in full shutdown or to enter full shutdown before the register settings will take effect. Currently the driver is not shutting down the device when a new audio route is created. If a new audio route is made active while there is already an active audio route, then the required register sequencing is violated. A hardware shutdown toggle when creating a new audio route corrects the sequencing error. The device must remain in hardware shutdown for 40ms to allow the internal hardware core to fully shutdown.
