From f4697bd7021f17ed540c16abafee72be73577826 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Fri, 23 Jun 2017 10:07:37 -0700 Subject: [PATCH] arm64: dts: rockchip: set rk3399 dynamic CPU power coefficients Provide the dynamic power coefficient of the big and little CPU clusters. These numbers are currently in use on the Samsung Chromebook Plus ("Kevin"). The power allocator thermal governor doesn't know how to do anything if it doesn't get power parameters from its cooling devices (in this case, CPUfreq). So this effectively enables the power-allocator governor.
