Intel Lightning Mountain SoC has a pinmux controller & GPIO controller IP which controls pin multiplexing & configuration including GPIO functions selection & GPIO attributes configuration. This IP is not based on & does not have anything in common with Chassis specification. The pinctrl drivers under pinctrl/intel/* are all based upon Chassis spec compliant pinctrl IPs. So this driver doesn't fit & can not use pinctrl framework under pinctrl/intel/* and it requires a separate new driver. Add a new GPIO & pin control framework based driver for this IP.

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.
