Uh, yeah.  I like the idea of a central repo for hardware info, and
the device tree concept is good.  My point is that the syntax, while
concise and exact, can be intimidating.  Just look at the amount of
traffic on the mailing lists of people that don't understand what all
the fields mean when specifying IRQs etc.  Anything we can do to make
it less so for noobies is a good thing for everybody.

Sure, no argument there -- enhancing the dts syntax with symbolic  
constants, computational expressions, and macros should make things like  
interrupt specifiers and maps a lot clearer.

Heh, I guess with the new dtc release out, I should have a serious
look at getting the long-mooted expression support ready to merge.
