Subject: [PATCH v3 4/4] arm64: dts: marvell: armada-37xx: add nodes allowing cpufreq support
Date: Wed, 13 Dec 2017 18:51:19 +0100	[thread overview]
Message-ID: <20171213175119.9441-5-gregory.clement@free-electrons.com> (raw)
In-Reply-To: <20171213175119.9441-1-gregory.clement-wi1+55ScJUtKEb57/3fJTNBPR1lH4CV8@public.gmane.org>

In order to be able to use cpu freq, we need to associate a clock to each
CPU and to expose the power management registers.
