Subject: [PATCH] dt-bindings: watchdog: allow "timer" as node name
Date: Mon, 12 Dec 2022 18:49:33 +0100 [thread overview]
Message-ID: <20221212174933.208900-1-krzysztof.kozlowski@linaro.org> (raw)
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".
