Subject: [PATCH v2 0/6] ALSA: cs35l56: Apply calibration from EFI

Factory calibration of the speakers stores the calibration information
into an EFI variable.

This set of patches adds support for applying speaker calibration
data from that EFI variable.

The HDA patch (#5) depends on the ASoC patches #2 and #3

Patch #6 is a KUnit test for the new cs-amp-lib library.

Richard Fitzgerald (6):
  ASoC: wm_adsp: Add wm_adsp_start() and wm_adsp_stop()
  ASoC: cs-amp-lib: Add helpers for factory calibration data
  ASoC: cs35l56: Add helper functions for amp calibration
  ASoC: cs35l56: Apply amp calibration from EFI data
  ALSA: hda: cs35l56: Apply amp calibration from EFI data
  ASoC: cs-amp-lib: Add KUnit test for calibration helpers
