Subject: [PATCH v3 25/27] ALSA: hda/cs8409: Remove unnecessary delays
Date: Fri, 30 Jul 2021 16:18:42 +0100 [thread overview]
Message-ID: <20210730151844.7873-26-vitalyr@opensource.cirrus.com> (raw)
In-Reply-To: <20210730151844.7873-1-vitalyr@opensource.cirrus.com>
From: Stefan Binding <sbinding@opensource.cirrus.com>
Since delays when starting jack detection after initialization
have been reduced/removed, it is necessary to add back in an extra
20ms delay after the init sequence to allow the CS42L42 to power up
correctly.
