Subject: [PATCH v4 0/3] ASoC: cs35l56: Replace open-coded SoundWire regmap with generic regmap-sdw
Date: Thu, 21 May 2026 12:54:17 +0100	[thread overview]
Message-ID: <20260521115420.978616-1-rf@opensource.cirrus.com> (raw)

This series replaces the entirely custom SoundWire regmap with the generic
regmap-sdw. The reasons for doing this are:

- Avoid code duplication
- Avoid effort of keeping custom implementation up-to-date
- Prepare for supporting BRA

Changes in V4:
- In patch #1 moved dereference of regmap_config after it has been
  checked for not-NULL.

Changes in V3:
- Change cs35l56-shared-test KUnit test to handle the offset addresses
  passed into its mock regmap bus.

Changes in V2:
- Select REGMAP_SOUNDWIRE

Richard Fitzgerald (3):
  ASoC: cs35l56-shared-test: Subtract reg_base offset in dummy regmap
  ASoC: cs35l56: Use reg_base to offset addresses on SoundWire
  ASoC: cs35l56: Use standard SoundWire regmap implementation
