Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to
- disable aldo2. On sun6i (A31) boards this is typically connected to
- VCC-PM, which powers the port M gpios, and should be set to 1.8V.
- On sun8i (A23) this is typically connected to VDD-DLL and must be
- set to 2.5V.
+ disable aldo2. On sun6i (A31) boards this is typically unused and

config AXP221_ALDO3_VOLT
int "axp221 aldo3 voltage"
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.
