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.
Patch #8 adds the ASoC driver.
Patches #9 and #10 add support for this to the Intel sof_sdw machine driver.
