Subject: [PATCH v5 06/10] ASoC: cs35l41: Create shared function for boost configuration
Date:   Thu, 16 Dec 2021 11:43:28 +0000
Message-ID: <20211216114332.153409-7-tanureal@opensource.cirrus.com>

Precedence: bulk

ASoC and HDA will use the same registers to configure
internal boost for the device
