Subject: [PATCH AUTOSEL 5.11 18/44] ASoC: cs42l42: Always wait at least 3ms after reset
Date: Thu, 25 Mar 2021 07:24:33 -0400 [thread overview]
Message-ID: <20210325112459.1926846-18-sashal@kernel.org> (raw)
In-Reply-To: <20210325112459.1926846-1-sashal@kernel.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.
