This driver is predominantly used by device tree systems, all of which can deal with modern GPIO descriptors. The legacy GPIO API is only used by one SH board so make the GPIO descriptor the default way to deal with it. As an intended side effect we do not need to look around in the device tree for the inversion flag since the GPIO descriptors will intrinsically deal with this.

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.
