Subject[PATCH] cpufreq: dt: Set default policy->transition_delay_ns
Date
The rate_limit_us for the schedutil governor is getting set to 500 ms by
default for the ARM64 hikey board. And its way too much, even for the
default value. Lets set the default transition_delay_ns to something
more realistic (10 ms), while the userspace always have a chance to set
something it wants.
