Subject: [PATCH] ASoC: rt5663: Add delay for jack plug in
Date: Wed, 30 Aug 2017 13:08:31 +0800 [thread overview]
Message-ID: <1504069711-6549-1-git-send-email-oder_chiou@realtek.com> (raw)
Codec initialize takes some time when 3.5mm jack plugged in. Add a
delay to report jack plugged event to user space to avoid pop noise.
