To ensure compatibility between user inputs and firmware requirements, a conversion mechanism is necessary for certain attributes. For instance, on some platforms, the DLVR frequency must be translated into a predefined index before being communicated to the firmware. On Lunar Lake platform: RFI_FREQ_SELECT and RFI_FREQ: Index 0 corresponds to a DLVR frequency of 2227.2 MHz Index 1 corresponds to a DLVR frequency of 2140 MHz Introduce a feature that enables the conversion of values between user space inputs and firmware-accepted formats. This feature would also facilitate the reverse process, converting firmware values back into user friendly display values. To support this functionality, a model-specific mapping table will be utilized. When available, this table will provide the necessary translations between user space values and firmware values, ensuring seamless communication and accurate settings.

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.
