Hi,

With new dtc+cpp feature, we could get rid of magic numbers in dts*
files. This patch replaces CLK IDs.

I wonder what sort of error message do you get when you make a mistake
in the .dts or one of the .dtsi includes? If cpp is handling the
including, does dtc just see a single file,

It is.

in which case are the line
numbers printed with each error not much use? Or does dtc handle the
#line directives?

cpp does generate #line directives, which dtc does know how to
interpret, so this should all work just fine. IIRC, I did test out this
aspect when adding #line support to dtc.
