41 config AXP221_DCDC1_VOLT
42 int "axp221 dcdc1 voltage"
43 depends on AXP221_POWER
46 Set the voltage (mV) to program the axp221 dcdc1 at, set to 0 to
47 disable dcdc1. This is typically used as generic 3.3V IO voltage for
48 things like GPIO-s, sdcard interfaces, etc. On most boards this is
49 undervolted to 3.0V to safe battery.
51 config AXP221_DCDC2_VOLT
52 int "axp221 dcdc2 voltage"
53 depends on AXP221_POWER
56 Set the voltage (mV) to program the axp221 dcdc2 at, set to 0 to
57 disable dcdc2. On A31 boards this is typically used for VDD-GPU,
58 on A23/A33 for VDD-SYS, this should normally be set to 1.2V.
60 config AXP221_DLDO1_VOLT
61 int "axp221 dldo1 voltage"
62 depends on AXP221_POWER
65 Set the voltage (mV) to program the axp221 dldo1 at, set to 0 to
66 disable dldo1. On sun6i (A31) boards with ethernet this is often used
67 to power the ethernet phy. On sun8i (A23) boards this is often used to

79 int "axp221 aldo1 voltage"
80 depends on AXP221_POWER
83 Set the voltage (mV) to program the axp221 aldo1 at, set to 0 to
84 disable aldo1. On sun6i (A31) boards which have a wifi module this is
85 often used to power the wifi module.

88 int "axp221 aldo2 voltage"
89 depends on AXP221_POWER
90 default 0 if MACH_SUN6I
91 default 2500 if MACH_SUN8I
93 Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to
94 disable aldo2. On sun6i (A31) boards this is typically unused and
95 should be disabled, if it is used for LPDDR2 it should be set to 1.8V.
96 On sun8i (A23) this is typically connected to VDD-DLL and must be set
