> +Order of Properties in Device Node
> +----------------------------------
> +
> +The following order of properties in device nodes is preferred:
> +
> +1. compatible
> +2. reg
> +3. ranges
> +4. Standard/common properties (defined by common bindings, e.g. 
> without
> +   vendor-prefixes)
> +5. Vendor-specific properties
> +6. status (if applicable)
> +7. Child nodes, where each node is preceded with a blank line

Another small suggestion...  It would be good to put the property names 
found in the list items, such as "compatible" and "status", into 
quotation marks, to make it obvious what they are.  That way, the list 
would also be more consistent with the property names mentioned in the 
sentence right below.
