From 9e985503ee4b23d576c303a17dfe52cfc8f32727 Mon Sep 17 00:00:00 2001 From: Jiaxin Yu Date: Fri, 27 Sep 2019 18:31:57 +0800 Subject: ASoC: mt8183: fix audio playback slowly after playback during bootup Before regmap_reinit_cache we must reset audio regs as default values. So we use reset controller unit(toprgu) to reset audio hw.
