Pinmux_pins[] is initialized through PINMUX_GPIO(), using designated
array initializers, where the GPIO_* enums serve as indices. If enum
values are defined, but never used, pinmux_pins[] contains (zero-filled)
holes. Such entries are treated as pin zero, which was registered
before, thus leading to pinctrl registration failures, as seen on
sh7722:
sh-pfc pfc-sh7722: pin 0 already registered
sh-pfc pfc-sh7722: error during pin registration
sh-pfc pfc-sh7722: could not register: -22
sh-pfc: probe of pfc-sh7722 failed with error -22
Remove GPIO_PH[0-7] from the enum to fix this.

README
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.
