Ack. It turned out that the pin controller is not strictly need for a bare minimum support of sd card booting, so it will be drop in patchset V2. A future patchset will re-introduce it when needed.

So also the name of the bindings namespace should not be this one controller IMO but the name of the family, bcm-stb-pinctrl.yaml or so. Yours, Linus Walleij

Missing commit msg. We can't take empty commits. You have entire commit
msg to describe the hardware, why not doing this?
Plus, this wasn't even tested...

Drop "Bindings for" and describe hardware. Bindings do not have to tell
they are bindings, it's obvious. They cannot be anything else.
