Hmm, I am not 100% sure about this.
Is there a case where resulted DTBs
depend on DTC version?
If I understand correctly,
DTS and DTB are 1:1
Unlike CC, there is no room for optimization.
Some possibilities could be:
- specification is updated.
( /dts-v1/ in DTS should be updated if so)
- buggy DTC version generates broken DTBs.
