According to binding-doc [1], the value of reg should be
" lower case hexadecimal with leading zeroes suppressed", I have
updated it at linux binding-doc in my patch.
Besides, you may have a dtsi for common parts for board and its derived
board, in that case, you only need to change one file next time, surely,
it is not related to this patch.
