Module Name: src
Committed By: jmcneill
Date: Sun Nov 29 16:52:00 UTC 2015
Modified Files:
src/sys/arch/arm/amlogic: amlogic_cpufreq.c amlogic_crureg.h
files.amlogic
src/sys/arch/evbarm/conf: ODROID-C1
Log Message:
Retire CPUFREQ option, instead just pick the highest available frequency
at boot. Update the list of supported frequencies to match the list of dvfs
frequencies from the meson8b dts, capped at 1.5GHz. The highest available
frequency is changed from 1512MHz to 1536MHz.
