If that's the only possible value,
This could be peripheral and otg in future.

Similar here, except this one is never a GPIO controller.
If the point to have #a = #s = 0 is to not have a unit-address
in the child nodes: you should do that simply by not specifying
a reg in the child nodes.
+y) LEDs on GPIOs
This one is so full of linux, stuff that I won't review it --
I wouldn't know where to start, sorry.
How about this version? (diff against the previous version is here,
and new full version will follow)
Doubts:
1. I removed linux,name and now Linux will use node's name. Is this
okay, or name property would be better?
2. I can't thinkout replacement for the linux,default-trigger, this is
really linux-specific. The value could be anything Linux implements
currently or will implement in the future...
