Here it would be nice to explain a little bit about the board and its features.

If you have a URL for the board, you can add it too.

Please add 'domintel' entry into
Documentation/devicetree/bindings/vendor-prefixes.txt in a separate

Please follow the style from arch/arm/boot/dts/imx28-tx28.dts, where
&ssp0 is used.

Do you mean "microchip,mcp7941x" instead?
