i.MX8ULP/93 GPIO supports similar feature as i.MX7ULP GPIO, but i.MX8ULP is actually not hardware compatible with i.MX7ULP. i.MX8ULP only has one register base, not two bases. i.MX8ULP and i.MX93 actually has two interrupts for each gpio controller, one for Trustzone non-secure world, one for secure world. Although the Linux Kernel driver gpio-vf610.c could work with fsl,imx7ulp-gpio compatible, it is based on some tricks did in device tree with some offset added to base address. Add a new of_device_id entry for i.MX8ULP. But to make the driver could also support old bindings, check the compatible string first, before check the device data.

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.
