From 8be87bf0639b3dfd79814d5e56c291ba09fb8288 Mon Sep 17 00:00:00 2001 From: Kai Vehmanen Date: Tue, 8 Oct 2019 11:44:35 -0500 Subject: [PATCH] ASoC: SOF: enable sync_write in hdac_bus [ Upstream commit f3416e7144f5d4ba0fc5dcef6ebfff891266c46a ] Align SOF HDA implementation with snd-hda-intel driver and enable sync_write flag for all supported Intel platforms in SOF. When set, a sync is issued after each verb write. Sync after write has helped to overcome intermittent delays in system resume flow on Intel Coffee Lake systems, and most recently probe errors related to the HDMI codec on Ice Lake systems. Matches the snd-hda-intel driver change done in commit 2756d9143aa5 ("ALSA: hda - Fix intermittent CORB/RIRB stall on Intel chips").
