[PATCH 0/2] ASoC: codecs: wcd937x: add USB Type-C analog audio mux support
From: Val Packett
Date: Sun Oct 18 2026 - 19:13:29 EST
Currently only wcd939x has support for USB-C SBU audio in mainline, but the
older WCD codecs can do the same thing 939x does with USBSS, with an
external 3rd party mux instead. This series adds support for that based on
wcd939x code.
Tested with the FSA4480 (with the [1] series) on sm7325-motorola-dubai.
