From 3dc4ba2067f2accfedb28e2cc2b136bb10cd671c Mon Sep 17 00:00:00 2001 From: Cheng-Yi Chiang Date: Mon, 28 Oct 2019 17:52:29 +0800 Subject: [PATCH] ASoC: rockchip: rockchip_max98090: Enable SHDN to fix headset detection max98090 spec states that chip needs to be in turned-on state to supply mic bias. Enable SHDN dapm widget along with MICBIAS widget to actually turn on mic bias for proper headset button detection. This is similar to cht_ti_jack_event in sound/soc/intel/boards/cht_bsw_max98090_ti.c. Note that due to ts3a227e reports the jack event right away before the notifier is registered, if headset is plugged on boot, headset button will not get detected until headset is unplugged and plugged. This is still an issue to be fixed.
