I believe we have settled on a final representation, it just hasn't been
added into linux-next yet. See:
http://gitorious.org/linux-pwm/linux-pwm/commit/d3ce73e5dc86646a6302f2b0f7dd40e8c552fa04

Equally, there's been extensive discussion re: how to represent the
NVIDIA display controller in DT. I strongly believe that U-Boot
shouldn't go ahead in isolation with a binding that's completely
unrelated to what's happening in the kernel. Please can you take what
Thierry is working on for the kernel, and/or contribute to that binding
etc., so we don't end up with multiple ways of doing the same thing.
Part of the whole point of DT is to have a single way of representing HW
that multiple OSs (or perhaps bootloaders) cna use. If everyone just
goes and does their own thing, we've lost.
