The CS35L54 and CS35L57 are Boosted Smart Amplifiers. The CS35L54 has I2C/SPI control and I2S/TDM audio. The CS35L57 also has SoundWire control and audio.
The hardware differences between L54, L56 and L57 do not affect the driver control interface so they can all be handled by the same driver.
The HDA patch has build dependencies on the ASoC patch.
The final patch updates serial-multi-instantiate and scan.c to trap the ACPI HID for HDA systems that declare multiple amps all under one Device() node. This patch does not have any build dependency on the first two patches so can be taken separately.
