From 87a6fe80d56be85bda093c4dd8a3e6535bda7e4a Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Tue, 2 Jul 2019 16:24:28 +0300 Subject: ASoC: SOF: Intel: implement runtime idle for CNL/APL Implement runtime idle for CNL/APL devices using similar runtime PM idle logic as the Intel AZX HDA driver. If any HDA codecs are powered when runtime suspend request comes, return -EBUSY. By doing this, strict ordering is enforced between HDA codec and the HDA controller.
