version control for dts/dtb?

version control for dts/dtb?

[marty]

Is there a  wy to figure out the version of the dtb file I'm  using?
At a minimum, it would be useful to have a node with the conversion time 
stuck somewhere...

I ran dtc to convert binary to source, but that isn't necessarily what I 
wanted to look at -- just a single date
code would be sufficient...

There is currently no direct version stamp in the
DTS or DTB files.  You may be able to derive some
knowledge by running a DTB file through the DTC
with the input file as "dtb" and looking at an
output file of DTS, though.  That is, "-I dtb -O dts"
and looking at it.

[Leisner, Martin]

I made a node "revision" which was tied into rcs...

 ...
        compatible =3D "mpc74xx";
        revision =3D "$Revision: 1.7 $";
        #address-cells =3D <1>;
        #size-cells =3D <1>;
        linux,phandle =3D <100>;
...

This seems to do what I wanted, I can then see in /proc/device-tree what
dts I'm running...
