My bot found errors running 'make dt_binding_check' on your patch:

/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/mtd/intel,lgm-nand.example.dt.yaml: nand-controller@e0f00000: '#address-cells', '#size-cells' do not match any of the regexes: '^nand@[a-f0-9]+$', 'pinctrl-[0-9]+'
/builds/robherring/linux-dt-review/Documentation/devicetree/bindings/mtd/intel,lgm-nand.example.dt.yaml: nand-controller@e0f00000: nand@0: '#address-cells', '#size-cells', 'nand-on-flash-bbt' do not match any of the regexes: 'pinctrl-[0-9]+'

See https://patchwork.ozlabs.org/patch/1299399

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure dt-schema is up to date:

pip3 install git+https://github.com/devicetree-org/dt-schema.git@master --upgrade

Please check and re-submit.
