make CHECK_DTBS=y st/stm32f469-disco.dtb brings up a warning about a missing argument: stm32f469-disco.dtb: pinctrl@40020000: st,syscfg:0: [21, 8] is too short The description of the third entry indicates that this entry is optional. The code in stm32_pctrl_dt_setup_irq parses st,syscfg and treats the third entry as optional. It defaults to 0xf if not present in the devicetree. Update the schema to require at least two entries, use the same syntax as the description of renesas,ipmmu-main in Documentation/devicetree/bindings/iommu/renesas,ipmmu-vmsa.yaml.

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.
