Continuous mode uses the PWM regulator's maximum and minimum supplied
voltages specified in the regulator-{min,max}-microvolt properties to
calculate appropriate duty-cycle values. This allows for a much more
fine grained solution when compared with voltage-table mode, which
this driver already supports. This solution does make an assumption
that a %50 duty-cycle value will cause the regulator voltage to run
at half way between the supplied max_uV and min_uV values.
Lee Jones (8):
ARM: STi: STiH407: Add PWM Regulator node
regulator: pwm-regulator: Remove unnecessary descriptor attribute from ddata
regulator: pwm-regulator: Remove superfluous is_enabled check
regulator: pwm-regulator: Diffientiate between dev (device) and rdev
(regulator_dev)
regulator: pwm-regulator: Don't assign structure attributes right away
regulator: pwm-regulator: Separate voltage-table initialisation
regulator: pwm-regulator: Add support for continuous-voltage
regulator: pwm-regulator: Re-write bindings
