Based on tag: next-20221006 linux-next/master, 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 MT8186, MT7986 and MT8195,
- Fix the watchdog name of mt8516
- Add mt6795 and MT8173 watchdog compatible
- Add support for toprgu reset on the MediaTek Helio X10 MT6795 SoC.
Changes since [1]:
- Drop "timeout-sec: true" and use unevaluatedProperties

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" and
"mediatek,mt8195-wdt". Since there is no reset controller for the mt6589,
we remove "mediatek,mt6589-wdt" as a fallback.
