[PATCH v4 02/17] dt-bindings: gpu: Add Imagination Technologies PowerVR GPU

[Conor Dooley]

Hey Sarah,

Your series does not appear to be threaded. `git send-email` can be
passed, for example, a directory containing a whole series & will set
the correct in-reply-to headers so that the series is in a single
thread.

The changelog should go below the --- line.

The description here doesn't add any value, since there is only one
interrupt, so you can drop it and do maxItems: 1 as you have done
elsewhere.

And this
items:
  - const: gpu
can just be
const: gpu

Although, if there is only one interrupt this is probably not
particularly helpful. Are there other implementations of this IP that
have more interrupts?

Otherwise, this looks good to me.

Thanks,
Conor.
