I see this is already in linux-next, and it has a warning:

Documentation/devicetree/bindings/sound/tas2780.example.dtb: codec@38: 'shutdown-gpios' does not match any of the regexes: 'pinctrl-[0-9]+'
	From schema: /builds/robherring/linux-dt/Documentation/devicetree/bindings/sound/tas2780.yaml

Please send a fix for this and the comments below.

No checks ran and no review happened because the DT list was not Cc'ed. 
Please use get_maintainers.pl for where to send patches.

Also the subjects need some work. Use 'git log --oneline <path>' for a 
idea of what the subject should start with. I imagine Mark fixed it for 
you.

Can be constraints instead:

items:
  - items:
      - minimum: 0x38
        maximum: 0x45

constraints? 0 - 2^32 is valid?
