Subject: [PATCH 2/3] ASoC: soc_sdw_utils: Add device info for CS47L47
Date: Mon, 23 Feb 2026 15:02:55 +0000 [thread overview]
Message-ID: <20260223150256.326143-3-rf@opensource.cirrus.com> (raw)
In-Reply-To: <20260223150256.326143-1-rf@opensource.cirrus.com>
Add a device info entry for the Cirrus Logic CS47L47.
CS47L47 has UAJ (headset speaker + mic + jack detect) and DMICs.
The audio ports are similar to the CS42L45 so can be based on the
CS42L45 code.
