Allow specifying the axp221 dcdc2 voltage via Kconfig, this is necessary because on some boards the 1.2V default does not work reliable. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

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.

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.

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.
