I poked at your series with the following script:

```
$ cat dtb-check
#!/usr/bin/bash

set -euo pipefail

DTB="$1"

rm -f arch/arm/boot/dts/"$DTB"
make CHECK_DTBS=y "$DTB" 2>&1 |
    sed "/should not be valid under {'type': 'object'}/d" > curr.log
diff -u ref.log curr.log
```

I ran this after creating a reference output prior to your series using
the same `make CHECK_DTBS=y` command.

This patch gave the following output (which I expect Rob's bot will
follow up with at some point as well):

```

Can you please address these and go over the rest of the patches to
shore them up against the current bindings?

Thanks,
