The TLV320ADC3001/3101 have an internal DSP, which can either be
used in various preset configurations (called "Processing Blocks"
in the data sheet), or as a freely programmable (using the
"PurePath Studio" graphical programming tool from TI) but rather
small DSP ("miniDSP").
Using the default configuration (PRB_R1) it's possible to set up
filtering using a first-order IIR, which can be useful for adding
a digital high pass filter to the signal chain, for instance.
This patch adds support for configuring the IIR filter coefficients.
The filter itself is always enabled; the default coefficients
implement a pass-through function.

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 Restructured Text 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.
