regulator: MAX8998: set_voltage bugfix. ramp_up delay and min/max voltage
Two issues are addressed for max8998_set_voltage function.
1. Min/Max Voltage.
max8998_set_voltage had been using the voltage value of
min ( voltage[i] >= max_vol , i )
This is corrected to use:
min ( voltage[i] >= min_vol , i )
2. Ramp Up Delay.
max8998_set_voltage should provide delay for BUCK1/2
if ENRAMP is on. It reads RAMP value from ONOFF4 register to determine
RAMP delay length. However, when max8998_set_voltage's new voltage is
lower than the previous, we don't care because it does not deteriorate
the stability.
Changes since v1:
- rebased onto latest regulator-for-next tree
