[PATCH v3 4/8] dt-bindings: watchdog: Add compatible for MediaTek mt8167

[Luca Leonardo Scorcia]

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 has 15 sw resets instead of 12, and the systems to which
each reset bit corresponds are different from mt6589, so the reset bit
constants are different too.

If the number of resets varies between SoCs, the watchdog driver becomes
incompatible. Update the wdt binding to add a dedicated compatible for
mt8167.
