I simply did not see that patch, thank you for pointing it out.

I believe both patches serve the same purpose - get DT validation for the
Broadcom Kona watchdog.

Looking at the two patches, there's very little difference:
 - capitalization of title (*F*amily *W*atchdog *T*imer)
 - maintainers
 - the brcm,bcm11351-wdt compatible listed as const vs. as enum with
   a single entry (I think the enum is better for future additions,
   but no strong opinion on that)
 - the other patch has a description (which IMO is unnecessary)

Since that patch came before mine, you can drop this one if you want.
