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.
