You mean _should not_ be documented in fsl.txt, right?
Ok, I have no problem with that, we've just used the same approach OMAP
takes - all the OMAP based boards are documented in the same file:
Documentation/devicetree/bindings/arm/omap/omap.txt

Do you think we should document it in:
Documentation/devicetree/bindings/arm/compulab-boards.txt
(this file should already exist in arm-soc/next/dt)?

I don't remember we've used this one before...
Can you please point to an example?

Ok. Will be done for the next version. Thanks!
