ALSA: hda: cs35l56: Add ACPI device match tables Adding the ACPI HIDs to the match table triggers the cs35l56-hda modules to be loaded on boot so that Serial Multi Instantiate can add the devices to the bus and begin the driver init sequence.

ALSA: hda: cs35l56: Add support for CS35L54 and CS35L57 Add the HID for the CS35L54 and CS35L57 Boosted Smart Amplifiers. These have the same control interface as the CS35L56 so are handled by the cs35l56-hda driver.

ALSA: hda/cs35l56: Use set/get APIs to access spi->chip_select In preparation for adding multiple CS support for a device, set/get functions were introduces accessing spi->chip_select in 'commit 303feb3cc06a ("spi: Add APIs in spi core to set/get spi->chip_select and spi->cs_gpiod")'. Replace spi->chip_select with spi_get_chipselect() API.

ALSA: hda: cs35l56: Enable low-power hibernation mode on SPI SPI hibernation is now supported with the latest hibernation/wake sequences in the shared ASoC code. This has a functional dependency on two commits: commit 3df761bdbc8b ("ASoC: cs35l56: Wake transactions need to be issued twice") commit a47cf4dac7dc ("ASoC: cs35l56: Change hibernate sequence to use allow auto hibernate") To protect against this, enabling hibernation is conditional on CS35L56_WAKE_HOLD_TIME_US being defined, which indicates that the new hibernation sequences are available.

ALSA: hda/cs35l56: Add driver for Cirrus Logic CS35L56 amplifier Add a driver for the Cirrus Logic CS35L56 amplifier. This uses the same component binding API as the CS35L41 driver. This is not a standalone HDA device; it provides control of the CS35L56 for systems that use a combination of an HDA codec and CS35L56 amplifiers with audio routed through the HDA codec. The CS35L56 combines a high-performance mono audio amplifier, Class-H tracking inductive boost converter, Halo Core(TM) DSP and a DC-DC boost converter supporting Class-H tracking. Control interfaces are I2C or SPI through the standard Linux I2C or SPI bus framework. Most chip functionality is controlled by on-board ROM firmware that is always running. Firmware patches can be applied by the driver in the form of a .wmfw file (firmware patch) and/or a .bin file (system tuning).
