The .data field in struct of_device_id is used as a const member so it's inappropriate to attach struct s32_pinctrl_soc_info with of_device_id because some members in s32_pinctrl_soc_info need to be filled by pinctrl-s32cc at runtime. For this reason, struct s32_pinctrl_soc_info must be allocated in pinctrl-s32cc and then create a new struct s32_pinctrl_soc_data in order to represent const .data in of_device_id. To combine these two structures, a s32_pinctrl_soc_data pointer is introduced in s32_pinctrl_soc_info. Besides, use of_device_get_match_data() instead of of_match_device() since the driver only needs to retrieve the .data from of_device_id.

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.
