The CS48L32 is an Audio DSP with microphone inputs and SPI control interface. It has a programmable DSP and a variety of power-efficient fixed-function audio processors, with configurable digital mixing and routing. Most properties are core properties: supply regulators, gpios, clocks, interrupt parent and SPI interface. The custom properties define the configuration of the microphone inputs to match what is physically attached to them.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
