I'm confused by this. Isn't devicetree at vger.kernel.org the place to discuss
device tree bindings? This is sent only to the U-Boot list, does this mean
that there will now be *two* ontologies for DT bindings? That sounds like
a recepie for ... something not good.

This is the real trick is it not?

Is the real commit blurb for this patch something like:

"we want a simple way to look up the clock frequency for our serial
ports during early boot, and following clocks = <&...> phandles
is too much trouble and might imply having to implement a whole
clock framework in U-Boot so we just see a lot of trouble, instead
provide a default frequency here"

I suggest in that case, instead do this:

- boot-frequency:
    input clock frequency at boot time, to be used by boot loaders
    and other early access.

This would be good for early Linux stuff as well I believe and I
do not think it's very controversial.

Yours,
