[PATCH 0/5] MediaTek watchdog: MT6795 support and YAML conversion

[AngeloGioacchino Del Regno]

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.

[PATCH 1/5] arm64: dts: mediatek: mt8186: Fix watchdog compatible

[AngeloGioacchino Del Regno]

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).

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.


[1] 
https://patchwork.kernel.org/project/linux-mediatek/list/?series=661669

[2] 
https://lore.kernel.org/all/20220920105622.25666-2-Runyang.Chen@mediatek.com/


Best regards,
Allen

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?

Regards,
Angelo

Hi Angelo,

I can send a new version with this series.

Thanks for help convert schema. 

Best regards,
