Just want to point out that i have used the same bindings for WDT and R_WDT.
I think it would be better to also introduce a bindings like
"allwinner,sun50i-h6-r-wdt", "allwinner,sun6i-a31-wdt";
We don't have access to the datasheet of this IP but we can strongly
suppose that wdt and r-wdt are the same.
What do you think?
Regards,
Clement
