    Subject[PATCH 5.10 557/563] dt-bindings: watchdog: Require samsung,syscon-phandle for Exynos7
    Date
    From: Sam Protsenko <semen.protsenko@linaro.org>

    commit 33950f9a36aca55c2b1e6062d9b29f3e97f91c40 upstream.

    Exynos7 watchdog driver is clearly indicating that its dts node must
    define syscon phandle property. That was probably forgotten, so add it.
