DP DMA has own power domain that's why describe optional power-domain
property.
As far as I understand, the property should always be specified, the
only reason why it's not mandatory is backward-compatibility (I would
make it mandatory, as I think proper validation of new DT is more
important than avoiding breaking validation - but not operation! - of
old DT, but that's a separate story). If my understanding is correct,
could you please update the example in the bindings to add the
power-domains property ?
backward compatible - of course
always specified - if pd driver is enabled it must be there. If not it doesn't
do anything - just describes it.
I am not in a position to decide this. But if dt folks agree with your ask I am
happy to make it mandatory and extend example.
