Enabling dtc interrupt_provider check reveals the examples are missing the "#interrupt-cells" property as it is a dependency of "interrupt-controller".

2024-09-02dt-bindings: gpio: simplify GPIO hog nodes schemaKrzysztof Kozlowski5-56/+0
The core schema in dtschema already strictly defines contents of nodes with "gpio-hog" property (with additionalProperties: false), thus the only thing device schema should do is: define "type: object" and required "gpio-hog". Make the code a bit simpler by removing redundant parts.

i.MX8ULP and i.MX93 actually has two interrupts for each gpio controller, one for Trustzone non-secure world, one for secure world. And they has one register based, not two as i.MX7ULP or VF610. 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.
