Improve the binding example by removing all the leading zeros to fix the following dtc warnings: Warning (unit_address_format): Node /XXX unit name should not have leading 0s Converted using the following command: perl -p -i -e 's/\@0+([0-9a-f])/\@$1/g' `find ./Documentation/devicetree/bindings "*.txt"` Some unnecessary changes were manually fixed.
