Subject: [PATCH v3 2/6] dt-bindings: soc: samsung: exynos-pmu: Require pmu-intr-gen-syscon for Exynos850
Date: Thu, 30 Apr 2026 02:56:52 +0100 [thread overview]
Message-ID: <20260430-exynos850-cpuhotplug-v3-2-fd6251d02a17@linaro.org> (raw)
In-Reply-To: <20260430-exynos850-cpuhotplug-v3-0-fd6251d02a17@linaro.org>
Update the Exynos PMU schema to mandate the 'google,pmu-intr-gen-syscon'
property for the 'samsung,exynos850-pmu' compatible so the driver can
obtain the necessary syscon regmap.
The Exynos850 PMU relies on a separate system controller block to handle
interrupts generation, similar to the hardware design of the GS101
SoC. To ensure the hardware is correctly described, this syscon phandle
must be explicitly provided.
