Subject: [PATCH v2 15/15] arm64: dts: exynos: Add CPU clocks for Exynos850
Date: Wed, 21 Feb 2024 21:02:35 -0600 [thread overview]
Message-ID: <20240222030235.27815-16-semen.protsenko@linaro.org> (raw)
In-Reply-To: <20240222030235.27815-1-semen.protsenko@linaro.org>
Define CPU cluster 0 and CPU cluster 1 CMUs, which generate CPU clocks,
and add corresponding CPU clocks to CPU nodes.
