Subject: [PATCH v5 5/7] dt-bindings: watchdog: mediatek: Convert mtk-wdt to json-schema

From: AngeloGioacchino Del Regno <[email protected]>

Convert the MediaTek watchdog bindings to schema.

The original binding only had 4 without a fallback but there is a reset
controller on the "mediatek,mt7986-wdt", "mediatek,mt8186-wdt",
"mediatek,mt8188-wdt" and "mediatek,mt8195-wdt" Since there is no reset
controller for the mt6589, we remove "mediatek,mt6589-wdt" as a
fallback.

As I'm put as the maintainer:
Acked-by: Matthias Brugger <[email protected]>

Shall I take that through my tree or shall it go through the watchdog tree?

In general, bindings should go via subsystem trees (so watchdog), just
like drivers. However this got Guenter's review tag, so usually it means
also an ack... Dunno... :)

For watchdog patches, if I send a Reviewed-by: tag, I expect Wim to pick
up the patch through the watchdog tree. If I expect some other tree to
pick it up, I use Acked-by: and usually add a note saying that I assume
that the patch will be picked up by someone else.

I usually also add watchdog patches to my own watchdog-next tree as
reference for Wim. I already have several mediatek devicetree patches
queued there. Handling some of the patches through watchdog and others
through some other tree would create a mess. Please don't do that.
