[PATCH v5 0/7] MediaTek watchdog: Convert mtk-wdt.txt to dt-schema

[PATCH v5 0/7] MediaTek watchdog: Convert mtk-wdt.txt to dt-schema

[Allen-KH Cheng]

Based on git/groeck/linux-staging.git, watchdog-next. 
We use [1] and [2] as references to send a new series.

This series converts mtk-wdt.txt to dt-schema and contains
- Fix watchdog compatibles for MT7986, MT8186, MT8188 and MT8195,
- Fix the watchdog name of mt8516
- Add mt6795 and MT8173 watchdog compatible

Changes since v4:
 - Drop label for watchdog node in mt8516

Changes since v3:
 - Drop label for watchdog example in yaml

Changes since v2:
 - Drop merged patch from series
 - Rebase to watchdog-next (for mt8188)

Changes since v1:
 - Drop "items" for a single enum·

Changes since [1]:
  - Update the commit message with some details
 - Drop "timeout-sec: true" and use unevaluatedProperties

[PATCH v5 1/7] arm64: dts: mediatek: mt8186: Fix watchdog compatible

[Allen-KH Cheng]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

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.

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

[Allen-KH Cheng]

From: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com>

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.

Acked-by: Matthias Brugger <matthias.bgg@gmail.com>

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.
