[PATCH] cpufreq: cppc: Use transition_delay_us depending on the transition_latency

2018-03-23 Thread George Cherian
With commit e948bc8fbee0 ("cpufreq: Cap the default transition delay value to 10 ms") the cpufreq was not honouring the delay passed via ACPI (PCCT). Due to which on ARM based platforms using CPPC the cpufreq governor tries to change the frequency of CPU faster than expeted. This leads to
