ARM: tegra: power: Limit CPU rate on system EDP alarm
System electrical design point (EDP) alarm is generated when system
power source (battery) over-current is detected.
Part of the system EDP management is CPU frequency capping added by
this commit. Maximum CPU clock frequency is pre-determined depending
on number of CPU cores on-line. It is combined with CPU regulator EDP
limit and applied to final CPU rate; CPU voltage is scaled down by
DVFS, respectively. The system EDP limit of CPU rate is removed after
alarm is canceled.
EDP event can be emulated via debugfs entry /d/cpu-tegra/edp_alarm.
