Subject[PATCH 05/11] PM / devfreq: governors: Return device frequency limits instead of user limits
Date
The performance, powersave and simpleondemand governors can return
df->min/max_freq, which are the user defined frequency limits.
update_devfreq() already takes care of adjusting the target frequency
with the user limits if necessary, therefore we can return
df->scaling_min/max_freq instead, which is the min/max frequency
supported by the device at a given time (depending on the
enabled/disabled OPPs)
