[PATCH v2 5/7] dt-bindings: watchdog: qcom-wdt: allow interrupts

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Both of type of watchdogs described in the binding (the KPSS watchdog
and APSS WDT timer) have interrupts.  Allow interrupts and describe them
for KPSS watchdog to fix warnings like:

  watchdog@17c10000: Unevaluated properties are not allowed ('interrupts' was unexpected)
