[PATCH 0/3] ASoC: cs35l56: More support for new Dell laptops

From: Richard Fitzgerald

Date: Thu Feb 05 2026 - 11:52:38 EST


Some new Dell models use spare pins on the amp as a binary integer
value to indicate the speaker type. The driver must use this to
select the correct firmware files for the hardware.

Patch #1 is the new support.
The other patches are for KUnit testing.

Richard Fitzgerald (3):
ASoC: cs35l56: Support for reading speaker ID from on-chip GPIOs
ASoC: cs35l56-shared: KUnit tests for onchip speaker ID gpios
ASoC: cs35l56: KUnit tests for parsing and using onchip GPIOs
