Read the "ngpios" property to determine the number of GPIOs for a bank. If not available, fallback to NMK_GPIO_PER_CHIP ie 32 ie the current behavior. The IP block always supports 32 GPIOs, but platforms can expose a lesser amount. The Mobileye EyeQ5 is in this case; one bank is 29 GPIOs and the other is 23.

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.
