+config AXP221_POWER
+       boolean "axp221 / axp223 pmic support"
+       depends on MACH_SUN6I || MACH_SUN8I
+       default y
+       ---help---
+       Say y here to enable support for the axp221 / axp223 pmic found on most
+       sun6i (A31) / sun8i (A23) boards.
+
+config AXP221_DCDC1_VOLT
+       int "axp221 dcdc1 voltage"
+       depends on AXP221_POWER
+       default 3000
+       ---help---
+       Set the voltage (mV) to program the axp221 dcdc1 at, set to 0 to
+       disable dcdc1. This is typically used as generic 3.3V IO voltage for
+       things like GPIO-s, sdcard interfaces, etc. On most boards this is
+       undervolted to 3.0V to safe battery.
+
+config AXP221_DCDC2_VOLT
+       int "axp221 dcdc2 voltage"
+       depends on AXP221_POWER
+       default 1200
+       ---help---
+       Set the voltage (mV) to program the axp221 dcdc2 at, set to 0 to
+       disable dcdc2. On A31 boards this is typically used for VDD-GPU,
+       on A23/A33 for VDD-SYS, this should normally be set to 1.2V.
+
+config AXP221_DLDO1_VOLT
+       int "axp221 dldo1 voltage"
+       depends on AXP221_POWER
+       default 0
+       ---help---
+       Set the voltage (mV) to program the axp221 dldo1 at, set to 0 to
+       disable dldo1. On sun6i (A31) boards with ethernet this is often used
+       to power the ethernet phy. On sun8i (A23) boards this is often used to
+       power the wifi.
+
+config AXP221_DLDO4_VOLT
+       int "axp221 dldo4 voltage"
+       depends on AXP221_POWER
+       default 0
+       ---help---
+       Set the voltage (mV) to program the axp221 dldo4 at, set to 0 to
+       disable dldo4.
+
+config AXP221_ALDO1_VOLT
+       int "axp221 aldo1 voltage"
+       depends on AXP221_POWER
+       default 0
+       ---help---
+       Set the voltage (mV) to program the axp221 aldo1 at, set to 0 to
+       disable aldo1. On sun6i (A31) boards which have a wifi module this is
+       often used to power the wifi module.
+
+config AXP221_ALDO2_VOLT
+       int "axp221 aldo2 voltage"
+       depends on AXP221_POWER
+       default 0 if MACH_SUN6I
+       default 2500 if MACH_SUN8I
+       ---help---
+       Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to
+       disable aldo2. On sun6i (A31) boards this is typically unused and
+       should be disabled, if it is used for LPDDR2 it should be set to 1.8V.
+       On sun8i (A23) this is typically connected to VDD-DLL and must be set
+       to 2.5V.
+
+config AXP221_ALDO3_VOLT
+       int "axp221 aldo3 voltage"
+       depends on AXP221_POWER
+       default 3000
+       ---help---
+       Set the voltage (mV) to program the axp221 aldo3 at, set to 0 to
+       disable aldo3. This is typically connected to VCC-PLL and AVCC and
+       must be set to 3V.
+
+config AXP221_ELDO3_VOLT
+       int "axp221 eldo3 voltage"
+       depends on AXP221_POWER
+       default 0
+       ---help---
+       Set the voltage (mV) to program the axp221 eldo3 at, set to 0 to
+       disable eldo3. On some A31(s) tablets it might be used to supply
+       1.2V for the SSD2828 chip (converter of parallel LCD interface
+       into MIPI DSI).
