Subject: [PATCH v2 4/8] arm64: dts: allwinner: h5: Add clock to CPU cores
Date:   Sat, 18 Jul 2020 00:00:49 +0800
Message-Id: <20200717160053.31191-5-wens@kernel.org>

From: Chen-Yu Tsai <wens@csie.org>

The ARM CPU cores are fed by the CPU clock from the CCU. Add a
reference to the clock for each CPU core, along with the clock
transition latency.
