Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.

This commit adds GPIO driver for Winbond Super I/Os. Currently, only W83627UHG model (also known as Nuvoton NCT6627UD) is supported but in the future a support for other Winbond models, too, can be added to the driver. A module parameter "gpios" sets a bitmask of GPIO ports to enable (bit 0 is GPIO1, bit 1 is GPIO2, etc.). One should be careful which ports one tinkers with since some might be managed by the firmware (for functions like powering on and off, sleeping, BIOS recovery, etc.) and some of GPIO port pins are physically shared with other devices included in the Super I/O chip.
