Subject: [alsa-devel] [PATCH 2/3] ASoC: dt-bindings: rt5682: add button delay device property
Date: Wed, 30 Oct 2019 16:55:56 +0800	[thread overview]
Message-ID: <20191030085556.14351-1-shumingf@realtek.com> (raw)

From: Shuming Fan <shumingf@realtek.com>

The btndet-delay device property could control the HW debounce time.
It is easy to adjust the sensitivity of push button.
