From 059c67f11c897a10e447d9802ace1a2069ae1b83 Mon Sep 17 00:00:00 2001 From: Shuming Fan Date: Wed, 30 Oct 2019 16:55:56 +0800 Subject: [PATCH] ASoC: dt-bindings: rt5682: add button delay device property The btndet-delay device property could control the HW debounce time. It is easy to adjust the sensitivity of push button.
