I ran the tests myself and it's only complaining about the ecc-engine name:

/home/user/src/kernels/linux/Documentation/devicetree/bindings/spi/mediatek,spi-mtk-snfi.example.dtb:
spi at 1100d000: 'ecc-engine' is a required property
>From schema: /home/user/src/kernels/linux/Documentation/devicetree/bindings/spi/mediatek,spi-mtk-snfi.yaml

It says nothing about the spi-nand part.
I'd like to keep the flash at 0 node in the example to demonstrate the
nand-ecc-engine usage. What should I do?
