Can you convert this binding to YAML? Would make it easier to see what
is applicable to certain compatibles.

Should remove the comma at the end of these lines so they don't have to
change.

Why is this so complicated? Would be better to just know that index 1 is
dp_com and index 0 is "normal" register base.

Please sort these lists based on compatible string.
