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.
