Subject: [PATCH 03/10] arm64: dts: allwinner: h5: Hook up cpu regulator supplies
Date: Wed, 30 Jan 2019 16:41:56 +0800
Message-ID: <20190130084203.25053-4-wens@csie.org> (raw)
In-Reply-To: <20190130084203.25053-1-wens@csie.org>

Some of the device trees for H5 boards already have the CPU supply
regulator defined, but they are not referenced in the CPU node.

Add the reference, so CPU DVFS mechanisms can see them.
