Subject: [PATCH v3 3/4] arm64: dts: allwinner: h6: Add clock to CPU cores
Date: Fri, 15 Feb 2019 10:53:37 -0500	[thread overview]
Message-ID: <20190215155338.10564-4-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20190215155338.10564-1-tiny.windzz@gmail.com>

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.
