When multiple components are connected back to back in an audio path, hw_param fixup may be required for CPU or Codec endpoint of BE<->BE DAI links. Currently fixup support is available for Codec and this commit adds similar feature for CPU endpoint of a BE<->BE link. For example a resampler component can be plugged into an audio path. [ FE -> BE1 -> ... -> resampler -> ... BEn ] The resampler DAI links can be: BEx (CPU) -> resampler input (Codec) resampler output (CPU) -> BEy (Codec) Thus input and output sample rate parameters for resampler can be fixed up as per the resample requirement.

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.
