'<&gpio1 parameters &gpio2 parameters>' and '<&gpio1 parameters>,
<&gpio2 parameters>' result in the same DTB, but second format has
better source code readability. Also 'dtbs_check' currently uses
this format to determine the amount of items specified, so using
this syntax is needed to successfully verify the devicetree source
against a DT schema format.
