Let's keep it simple, we want to enable this only for below ones Enable what? None of these explains why do you need this entry alone, since it is covered by list further. > > properties: > compatible: > enum: > - marvell,cn10k-wdt > - marvell,octeontx2-wdt > > Are you good with that? Not sure, it sounds like it ignores our entire discussion. What's the name of the SoC? I see "OcteonTx2 CN9130", not "OcteonTx2". I linked your previously guide how to write bindings. Did you read it? Best regards, Krzysztof
