Tan Jui Nee 7064d7d88b mfd: lpc_ich: Add support for pinctrl in non-ACPI system
Add support for non-ACPI systems, such as system that uses
Advanced Boot Loader (ABL) whereby a platform device has to be created
in order to bind with pin control and GPIO.

At the moment, Intel Apollo Lake In-Vehicle Infotainment (IVI) system
requires a driver to hide and unhide P2SB to lookup P2SB BAR and pass
the PCI BAR address to GPIO.

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.
