Based on tag: next-20221007 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 v1:
 - Drop "items" for a single enum 

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