From db30fce1eea58e50ae8b2722704b4f529c394dba Mon Sep 17 00:00:00 2001
From: Maxime Ripard <maxime.ripard@free-electrons.com>

Subject: [PATCH 5/5] ARM: sun5i: chip: Add CPU regulator for cpufreq

The current DT doesn't have a phandle to the CPU regulator in the CPU node,
which disables the CPU voltage scaling entirely.

Add that phandle.
