Hi Roman,

Thanks for looking.

The vendor kernel for this SoC binds the watchdog with the same
compatible list ("mediatek,mt6895-wdt", "mediatek,mt6589-wdt") at the
same address, and its register definitions are identical to mtk_wdt.c.

The TOPRGU reset layout is the one thing I can't confirm, as I found no
reset table for MT6895 there. This series does not use it: the DT has
no #reset-cells and no consumers. If reset lines are needed later, I
will add a dedicated mt6895_data to the driver.

I also tested the watchdog on the device: while userspace keeps
kicking it, the system stays up, and once the kicks stop the watchdog
resets the board after the timeout.

Best regards,
Alexander
