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) Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Reviewed-by: Rob Herring <robh@kernel.org> --- Changes since v1: 1.
