Subject: [PATCH v3 6/6] arm64: dts: exynos850: add PMU interrupt generation node
Date: Thu, 30 Apr 2026 02:56:56 +0100 [thread overview]
Message-ID: <20260430-exynos850-cpuhotplug-v3-6-fd6251d02a17@linaro.org> (raw)
In-Reply-To: <20260430-exynos850-cpuhotplug-v3-0-fd6251d02a17@linaro.org>
Add pmu_intr_gen node for Exynos850. This hw block is required
for different power management routines like CPU hotplug and
different sleep and idle states.
Also reference this node from main PMU node.
