Keep in mind that I'm still using legacy platform drivers and clocking, no dt's or common clock frame work. My issue begins with the inclusion of stuct cpufreq_frequency_table into struct cpufreq_policy, as part of the move from percpu to per-policy in the api. In 3...
The porblem is in [ drivers/cpufreq/imx-cpufreq-dt.c ], imx_cpufreq_dt_probe function,where it silently bails out if it can not find the 'cpu-power' property.Disabling the code that checks for this property, makes probe imx_cpufreq_dt_probe succeed,which in return ...
