+ default AXP_ALDO3_VOLT_SLOPE_NONE
+ ---help---
+ The AXP can slowly ramp up voltage to reduce the inrush current when
+ changing voltages.
+ Note, this does not apply when enabling/disabling LDO3. See
+ "axp pmic (a)ldo3 inrush quirk" below to enable a slew rate to limit
+ inrush current on broken board designs.

+config AXP_ALDO3_VOLT_SLOPE_16
+ bool "1.6 mV per uS"
+ ---help---
+ Increases the voltage by 1.6 mV per uS until the final voltage has
+ been reached. Note that the scaling is in 25 mV steps and thus
+ the slew rate in reality is about 25 mV/31.250 uS.
+
+config AXP_ALDO3_VOLT_SLOPE_08
+ bool "0.8 mV per uS"
+ ---help---
+ Increases the voltage by 0.8 mV per uS until the final voltage has
+ been reached. Note that the scaling is in 25 mV steps however and thus
+ the slew rate in reality is about 25 mV/15.625 uS.
+ This is the slowest supported rate.

+ The reference design denotes a value of 4.7 uF for the output capacitor
+ of LDO3. Some boards have too high capacitance causing an inrush current
+ and resulting an AXP209 shutdown.
