Subject: [PATCH 09/10] arm64: dts: allwinner: h5: Add clock to CPU cores
Date: Wed, 30 Jan 2019 16:42:02 +0800 [thread overview]
Message-ID: <20190130084203.25053-10-wens@csie.org> (raw)
In-Reply-To: <20190130084203.25053-1-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.
