I mean to say replaced soc family name from compatible with actual soc names

Thanks for pointing, I am sorry, missed almost all comments on v7. Will resolve this and below as well in next version

Not sure I understand this comment, Compatible in last version was as below:

+ properties:
+ compatible:
+ oneOf:
+ - const: marvell,octeontx2-wdt
+ - items:
+ - enum:
+ - marvell,octeontx2-95xx-wdt
+ - marvell,octeontx2-96xx-wdt
+ - marvell,octeontx2-98xx-wdt
+ - const: marvell,octeontx2-wdt
+ - const: marvell,cn10k-wdt
+ - items:
+ - enum:
+ - marvell,cn10kx-wdt
+ - marvell,cnf10kx-wdt
+ - const: marvell,cn10k-wdt

By fallback do you mean " const: marvell,cn10k-wdt" and " const: marvell,octeontx2-wdt" ? If yes I removed because "octeontx2" and "cn10k" are soc family name and no a specific soc.

Thanks
