Subject: [PATCH] ARM: dts: exynos: Add missing CPU clocks to secondary CPUs on Exynos542x
Date: Wed, 30 May 2018 18:49:22 +0200 [thread overview]
Message-ID: <20180530164922.31851-1-krzk@kernel.org> (raw)
Secondary CPUs should have the same information in DeviceTree as booting
CPU from both correctness point of view and for possible hotplug
scenarios.
Suggested-by: Viresh Kumar <viresh.kumar@linaro.org>
