With:
make dt_binding_check -j32 -s -W 2

I get the following output:

/home/ryan/Projects/Develop/RG35XX+/kernel/linux/Documentation/devicetree/bindings/display/panel/anbernic,wl-355608-a8.example.dtb: spi: 'num-chipselects' is a required property
	from schema $id: http://devicetree.org/schemas/spi/spi-gpio.yaml#
/home/ryan/Projects/Develop/RG35XX+/kernel/linux/Documentation/devicetree/bindings/display/panel/anbernic,wl-355608-a8.example.dtb: spi: 'sck-gpios' is a required property
	from schema $id: http://devicetree.org/schemas/spi/spi-gpio.yaml#

The relevant section from spi-gpio.yaml seems to be:

required:
  - compatible
  - num-chipselects
  - sck-gpios

I am happy to leave this out if a simpler example is desired, but alternately if the chipselects/sck-gpios should stay then I would suggest a better example would include the mosi/miso/cs GPIOs as well which would make the example functional.
