Folks,

Dave and I have finally comes to an agreement [*1*] about
the new format for some literals in DTS files as supported
by the Device Tree Compiler.

With that, I have just pushed out some changes to the DTC
repository on jdl.com [*2*] that supports the new /dts-v1/
formatted files with C-like literal support.

I encourage everyone to upgrade to this version of the DTC
as soon as they can.  Log messages for the three relevant
commits implementing it are below [*3*].

Please let me know if you have any problems with it!

Thanks,
jdl

    dtc: -Odts produces v1 output
    
    This patch alters the -Odts mode output so that it uses dts-v1 format.
    This means that dtc -Idts -Odts used on a v0 dts file will convert
    that file to v1.

    dtc: Switch dtc to C-style literals
    
    This patch introduces a new version of dts file, distinguished from
    older files by starting with the special token /dts-v1/.  dts files in
    the new version take C-style literals instead of the old bare hex or
    OF-style base notation.  In addition, the "range" for of memreserve entries
    (/memreserve/ f0000-fffff) is no longer recognized in the new format.

    dtc: Simplify lexing/parsing of literals vs. node/property names
    
    The current scheme of having CELLDATA and MEMRESERVE states to
    recognize hex literals instead of node or property names is
    arse-backwards.  The patch switches things around so that literals are
    lexed in normal states, and property/node names are only recognized in
    the special PROPNODENAME state, which is only entered after a { or a
    ;, and is left as soon as we scan a property/node name or a keyword.
