[PATCH v5 5/8] arm64: dts: mt8167: Properly describe the SoC watchdog resets

[Luca Leonardo Scorcia <l.scorcia@gmail.com>]

Currently mt8167 inherits its watchdog from the included mt8516 dtsi,
which in turn falls back on mt6589-wdt. However according to the data
sheet mt8167 toprgu is not really compatible with mt6589 (it has 14 sw
resets instead of 12, and the reset IDs are different from mt6589).

Use the dedicated mediatek,mt8167-wdt compatible for the watchdog driver,
as it correctly describes the SoC resets.
