Subject[PATCH v2 7/7] dt-bindings: watchdog: allow "timer" as node name
Date
On some SoCs the watchdog device is actually mixed with timer, e.g.
the qcom,msm-timer on older Qualcomm SoCs where this is actually one
hardware block responsible for both system timer and watchdog.

Allow calling such device nodes as "timer".
