Subject: [PATCH v5 1/9] arm64: dts: allwinner: h6: Add clock to CPU cores
Date: Mon, 20 Apr 2020 15:00:13 +0200	[thread overview]
Message-ID: <20200420130021.3841-2-peron.clem@gmail.com> (raw)
In-Reply-To: <20200420130021.3841-1-peron.clem@gmail.com>

From: Yangtao Li <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.
