I added the clock-frequency property to quell the following messages: [ 0.003273] /cpus/cpu@f00 missing clock-frequency property [ 0.003323] /cpus/cpu@f01 missing clock-frequency property [ 0.003352] /cpus/cpu@f02 missing clock-frequency property [ 0.003382] /cpus/cpu@f03 missing clock-frequency property I think they are from parse_dt_topology() in arch/arm/kernel/topology.c What do you suggest?
