-- interrupt-controller: Marks the device node as a interrupt controller.
- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
the IRQ output as open drain active low.

The mcp23s08 device and friends are interrupt /client/ nodes, and should not reference the interrupt controller device tree properties "interrupt-controller" and "interrupt-cells" [0]. Remove the confusing "interrupt-controller" and "interrupt-cells" properties from the pinctrl-mcp23s08 devicetree bindings documentation.
