[PATCH v2 0/8] ASoC: Initial support for Cirrus Logic CS35L56

From: Richard Fitzgerald
Date: Mon Mar 13 2023 - 11:50:56 EST


The CS35L56 is a high-performance boosted mono audio amplifier.
Supported control interfaces are I2C, SPI or SoundWire.
Supported audio interfaces are I2S/TDM or SoundWire.

The CS35L56 has a self-booting firmware in ROM, with the ability
to patch the firmware and/or apply tunings.
Patches #1 to #7 add support to cs_dsp and wm_adsp for self-booting
firmware and the ability to apply a .bin file without having to
apply a .wmfw.

Changes since v1:
- Check for error when getting pm_runtime in cs35l56_irq().
- Use SND_SOC_DAIFMT_CLOCK_PROVIDER_MASK instead of the old define.
- Re-word two comments in cs35l56-sdw.c.
- Add an comment explaining the wait for init_completion in
cs35l56_dsp_work().
- Omit patches to Intel machine driver. These will be done as a
separate thread.

ASoC: cs35l56: Add driver for Cirrus Logic CS35L56

Simon Trimmer (7):
firmware: cs_dsp: Introduce no_core_startstop for self-booting DSPs
ASoC: wm_adsp: Use no_core_startstop to prevent creating preload
control
firmware: cs_dsp: Support DSPs that don't require firmware download
ASoC: wm_adsp: Support DSPs that don't require firmware download
ASoC: wm_adsp: Expose the DSP boot work actions as wm_adsp_power_up()
ASoC: wm_adsp: Add support for loading bin files without wmfw
ASoC: wm_adsp: Simplify the logging of requested firmware files
