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 6bd9dcf339ebb292fa149ee0e52ea3c9d9822553 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Thu, 3 Nov 2016 17:07:19 +0530 Subject: [PATCH] ASoC: Intel: Skylake: Add support for specifying D0i3 configuration Not all use cases can support Doi3. Only certain use cases like hot word detection, deep buffering can support D0i3 based on resource requirement. So, pass the D0i3 capability for the FE/BE copier using topology. This will be used to take a decision for D0i3 mode entry/exit.
