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 f1ec5ec7a94ba8138f9cbdc1e9e3b03aee29c4df Mon Sep 17 00:00:00 2001 From: Liam Girdwood Date: Wed, 9 Sep 2015 12:10:31 +0100 Subject: [PATCH] ASoC: intel: Fix SSP port configuration after RTD3 resume. Currently the SSP port settings are being clobbered as part of the DSP RTD3 restore logic. make sure we save the correct params and restore them at resume. The FW sadly does not save SSP settings as part of the PM context.
