This change does not match the others? I do not think ::= is some kind
of malformed YAML that has crept into a literal block. Instead, I think
it is syntax inspired from BNF or something such. IIRC, it was once
adapted from
Documentation/devicetree/bindings/pwm/pwm.txt

Or, I am missing something...
