From: Daniel Schultz d.schultz@phytec.de Date: Tue, 13 Feb 2018 10:44:32 +0100 Subject: ARM: dts: rockchip: Remove 1.8 GHz operation point from phycore som
From: Daniel Schultz d.schultz@phytec.de
commit 5ce0bad4ccd04c8a989e94d3c89e4e796ac22e48 upstream.
Rockchip recommends to run the CPU cores only with operations points of 1.6 GHz or lower.
Removed the cpu0 node with too high operation points and use the default values instead.
