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).
