From b6c1bd37f8d539607e0f0487f3a6e5c3e6e885a2 Mon Sep 17 00:00:00 2001 From: Shuming Fan Date: Fri, 19 Jul 2019 14:32:49 +0800 Subject: [PATCH] ASoC: rt1308: add silence detection and manual PDB control We enable the silence detection function in initial settings. PDB control changes to manual mode, hence the driver could fully control the AMP output on/off.
