Subject: [PATCH 4.14 10/52] ASoC: cs42l42: Always wait at least 3ms after reset
Date: Mon, 5 Apr 2021 10:53:36 +0200 [thread overview]
Message-ID: <20210405085022.337043554@linuxfoundation.org> (raw)
In-Reply-To: <20210405085021.996963957@linuxfoundation.org>
From: Lucas Tanure <tanureal@opensource.cirrus.com>
[ Upstream commit 19325cfea04446bc79b36bffd4978af15f46a00e ]
This delay is part of the power-up sequence defined in the datasheet.
A runtime_resume is a power-up so must also include the delay.
