Subject: [PATCH v2 1/4] dt-bindings: clock: exynosautov920: add cpucl1/2 clock definitions
Date: Mon, 28 Apr 2025 20:35:14 +0900 [thread overview]
Message-ID: <20250428113517.426987-2-shin.son@samsung.com> (raw)
In-Reply-To: <20250428113517.426987-1-shin.son@samsung.com>
Add cpucl1 and cpucl2 clock definitions.
CPUCL1/2 refer to CPU Cluster 1 and CPU Cluster 2,
which provide clock support for the CPUs on Exynosauto V920 SoC.
