I don't see any .dts file really doing this. There are some imx*.dtsi
files that include imx*.h files, but I don't see these headers being
included in any source code file.
In fact, we already have all these values defined in
include/linux/wl12xx.h, so it could be nice to reuse. But the
cross-directory includes would look "funny". And I think it's a bit
overkill.
These values are actually used by the firmware itself, not only the
driver, so they are also platform independent and not related to the OS.
