I can add the following para to the patch description if you ack:

===========================================================================
Background:

Since 2011's update to scripts/dtc/dtc-lexer.l, we only support the
/dts-v1/ format which mandates "0x" for hex values. Practically,
literals (<V1>[0-9]+|0[xX][0-9a-fA-F]+ -> DT_LITERAL) are handled via
strtoull() with base==0 ("auto"), while we previously also had a
DT_LEGACYLITERAL (<INITIAL>[0-9a-fA-F]+), forcing base==16. Not anymore.
===========================================================================

Thanks in advance,

Roland
