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 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

MT8195's watchdog embeds a reset controller and needs only the
mediatek,mt8195-wdt compatible string as the MT6589 one is there
for watchdogs that don't have any reset controller capability.

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.

I think you missed my comment about renaming the label as well on the previous
