Thank you, Rob. There are similar microchip, pic32mzda patches related to spi,
sqi & rtc which are reviewed/acknowledged.

1. microchip,pic32mzda-spi.yaml
https://lore.kernel.org/all/20260622-ingenious-finch-of-fantasy-7bafaf@quoll/

2. microchip,pic32mzda-sqi.yaml
https://lore.kernel.org/all/20260625-omen-stark-6bb827ebcc43@spud/

3. microchip,pic32mzda-rtc.yaml
https://lore.kernel.org/all/20260703-identify-cringe-ef88079923cd@spud/

Please let me know if any further action is required from my end to
merge in the
mainline.

Regards,
Udaya Kiran Challa

I picked up watchdog only because watchdog DT patches have a tendency to 
get missed.

You missed sending to linux-spi and/or Mark B on these. You'll need to 
send another version.

You missed Alexandre.

In general, use what get_maintainers.pl gives you.
