This change adds support for static calibration data via ASoC topology
file. This static calibration data could include binary blob of data
that is required by specific module and is not part of topology tokens.
Reason for adding this support is to allow loading module specific data
that can not be part of the tplg tokens, example, Echo and Noise cancelling
module needs a blob of calibration data to function correctly.
This support is also one of the building block for adding speaker
protection support.
Tested this with Single Mic ECNS(Echo and Noise Cancellation).
tplg can now contain this calibration data like:
SectionWidget."stream2.SMECNS_V224" {
...
data [
...
"stream2.SMECNS_V224_cfg_data"
]
}
SectionData."stream2.SMECNS_V224_cfg_data" {
words "0x00000330, 0x01001006,0x00000000,0x00000000,
0x00004145,0x08001026,0x00000004,0x00000000,
..."
}
}

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.
