[PATCH 2/3] ASoC: soc_sdw_utils: Add device info for CS47L47
From: Richard Fitzgerald
Date: Mon Feb 23 2026 - 10:04:41 EST
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.
