This series converts mtk-wdt.txt to dt-schema, fixes watchdog compatibles
for MT8186 and MT8195, and adds support for the watchdog and toprgu reset
found on the MediaTek Helio X10 MT6795 SoC.

MT8186's watchdog embeds a reset controller and needs only the
mediatek,mt8186-wdt compatible string as the MT6589 one is there
for watchdogs that don't have any reset controller capability.

The original binding only had 4 without a fallback. It's fine to add or
change, but note the changes in the commit msg. Are all of these really
each unique and not the same?

Ok I will note the changes in the commit for v2. And... yes, they're really
each unique and not the same, as these are exposing a reset controller of
their own (as well with different platform data in the driver).

There is already work in progress:

Best regards,

Hi Krzysztof,
Thanks for the reminder.
There is also a series [1] for mediatek watchdog.
I would have to wait until [2] merged before sending a series for
"Convert mtk-wdt" in order to prevent a conflict, but [2] has not yet
been merged.

I'm sorry, I forgot about that.
Allen, how do we proceed? Do you want to send a new version of yours, or should
I go on with a v2 for this one?

Hi Angelo,
I can send a new version with this series.
Thanks for help convert schema.
