This more a first glance, I didn't check every binding, but already found
some dubious ones, so in general, please make sure to only include nodes
with approved bindings.

please provide a binding addition for the board in a separate patch as well.

if possible, please rebase on top of my for-next branch, as we also
have the first gru board in there now.

Just to make sure, is this really a Rockchip board? I would've expected
to see something like "firefly,firefly-rk3399" here, like on the rk3288-
variant. Not a requirement, just a question to clarify who designed the
board please :-) .

Thanks to Andy's persistence, we have nice constants in the pinctrl-
binding-header now, like RK_PB2 for the above. So you can drop the
comment and use the constant instead for easier reading.
Same for other pins.

that is not a valid binding, am I right? ;-)
So should be dropped.
