Subject: [PATCH 1/8] dt-bindings: soc: samsung: exynos-pmu: allow phys as child
Date:   Fri, 27 Jan 2023 20:40:50 +0100
Message-Id: <20230127194057.186458-2-krzysztof.kozlowski@linaro.org>
In-Reply-To: <20230127194057.186458-1-krzysztof.kozlowski@linaro.org>

Precedence: bulk

The MIPI and DisplayPort phys are actually part of the Power Management
Unit system controller, thus allow them as its children, instead of
specifying as separate device nodes with syscon phandle.
