Will fix that. BTW, I tried running make dtbs_check and faced a few
errors on other yaml files (which is why I ended up sending the patch
without fully validating the schema). Maybe those have been fixed (I'm
based on the media tree which is based on 5.4-rc1).

Oh, and I also noticed that the generated example has
#address-cells = <1>, #size-cells = <1> in the parent node, while my
example expects <2>. Is there any way I can specify that somewhere, or
should I just tweak the example to use 1 cell instead?
