This is typically used as generic 3.3V IO voltage for 22 things like GPIO-s, sdcard interfaces, etc. On most boards this is 23 undervolted to 3.0V to safe battery. 24 25config AXP221_DLDO1_VOLT 26 int "axp221 dldo1 voltage" 27 depends on AXP221_POWER 28 default 0 29 ---help--- 30 Set the voltage (mV) to program the axp221 dldo1 at, set to 0 to 31 disable dldo1. On sun6i (A31) boards with ethernet this is often used 32 to power the ethernet phy. On sun8i (A23) boards this is often used to 33 power the wifi. 34 35config AXP221_DLDO4_VOLT 36 int "axp221 dldo4 voltage" 37 depends on AXP221_POWER 38 default 0 39 ---help--- 40 Set the voltage (mV) to program the axp221 dldo4 at, set to 0 to 41 disable dldo4. 42 43config AXP221_ALDO1_VOLT 44 int "axp221 aldo1 voltage" 45 depends on AXP221_POWER 46 default 0 47 ---help--- 48 Set the voltage (mV) to program the axp221 aldo1 at, set to 0 to 49 disable aldo1. On sun6i (A31) boards which have a wifi module this is 50 often used to power the wifi module. 51 52config AXP221_ALDO2_VOLT 53 int "axp221 aldo2 voltage" 54 depends on AXP221_POWER 55 default 0 if MACH_SUN6I 56 default 2500 if MACH_SUN8I 57 ---help--- 58 Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to 59 disable aldo2. On sun6i (A31) boards this is typically unused and 60 should be disabled, if it is used for LPDDR2 it should be set to 1.8V. 61 On sun8i (A23) this is typically connected to VDD-DLL and must be set 62 to 2.5V. 63 64config AXP221_ALDO3_VOLT 65 int "axp221 aldo3 voltage" 66 depends on AXP221_POWER 67 default 3000 68 ---help--- 69 Set the voltage (mV) to program the axp221 aldo3 at, set to 0 to 70 disable aldo3. This is typically connected to VCC-PLL and AVCC and 71 must be set to 3V. 72 73config AXP221_ELDO3_VOLT 74 int "axp221 eldo3 voltage" 75 depends on AXP221_POWER 76 default 0 77 ---help--- 78 Set the voltage (mV) to program the axp221 eldo3 at, set to 0 to 79 disable eldo3. On some A31(s) tablets it might be used to supply 80 1.2V for the SSD2828 chip (converter of parallel LCD interface 81 into MIPI DSI). 82 83endmenu 84
