| 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_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). |
