When PINCTRL_BCM2835 is enabled and GPIOLIB is disabled, it results in the
following Kbuild warning:
WARNING: unmet direct dependencies detected for GPIOLIB_IRQCHIP
Depends on [n]: GPIOLIB [=n]
Selected by [y]:
- PINCTRL_BCM2835 [=y] && PINCTRL [=y] && OF [=y] && (ARCH_BCM2835 [=n] || ARCH_BRCMSTB [=n] || COMPILE_TEST [=y])
The reason is that PINCTRL_BCM2835 selects GPIOLIB_IRQCHIP without
depending on or selecting GPIOLIB while GPIOLIB_IRQCHIP is subordinate to
GPIOLIB.
Honor the kconfig menu hierarchy to remove kconfig dependency warnings.

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.
