[PATCH 0/2] ASoC: cs35l56: Consider SDCA FunctionExtension ID/Version for firmware name

From: Richard Fitzgerald

Date: Tue Nov 10 2026 - 12:05:30 EST


This series is a change to the cs35l56 driver with corresponding KUnit
test code. It considers the SDCA FunctionExtension ID/Version as variant
identification when searching for a suitable firmware. The intepretation
of these values matches the way Windows interprets them for the same
available set of hardware identifiers, to ensure compatible firmware
identification.

ASoC: cs35l56: Add KUnit tests for FEID and FEV firmware names
