Fairchild FAN53555 and its clone from Rockchip, Silergy and TCS support
two modes of operation:
- Auto-PFM: Allow automatic PFM during light load (default mode)
- Forced PWM
Some boards require forced PWM mode to keep the supply ripple within
acceptable limits under light load conditions.
Regulator mode indexes are starting from 1 to keep backward compatibility
with existing device trees
