57 regulator-ramp-delay:
58 description: ramp delay for regulator(in uV/us) For hardware which supports
59 disabling ramp rate, it should be explicitly initialised to zero (regulator-ramp-delay
63 regulator-enable-ramp-delay:
67 required due to the combination of internal ramping of the regulator
72 regulator-settling-time-us:
73 description: Settling time, in microseconds, for voltage change if regulator
75 when regulator have exponential voltage change.
77 regulator-settling-time-up-us:
79 the regulator needs a constant time to settle after voltage increases
