1config AXP221_POWER 2 boolean "axp221 / axp223 pmic support" 3 depends on MACH_SUN6I || MACH_SUN8I 4 default y 5 ---help--- 6 Say y here to enable support for the axp221 / axp223 pmic found on most 7 sun6i (A31) / sun8i (A23) boards. 8 9config AXP221_DCDC1_VOLT 10 int "axp221 dcdc1 voltage" 11 depends on AXP221_POWER 12 default 3000 13 ---help--- 14 Set the voltage (mV) to program the axp221 dcdc1 at, set to 0 to 15 disable dcdc1. This is typically used as generic 3.3V IO voltage for 16 things like GPIO-s, sdcard interfaces, etc. On most boards this is 17 undervolted to 3.0V to safe battery. 18 19config AXP221_DLDO1_VOLT 20 int "axp221 dldo1 voltage" 21 depends on AXP221_POWER 22 default 0 23 ---help--- 24 Set the voltage (mV) to program the axp221 dldo1 at, set to 0 to 25 disable dldo1. On sun6i (A31) boards with ethernet this is often used 26 to power the ethernet phy. On sun8i (A23) boards this is often used to 27 power the wifi. 28 29config AXP221_DLDO4_VOLT 30 int "axp221 dldo4 voltage" 31 depends on AXP221_POWER 32 default 0 33 ---help--- 34 Set the voltage (mV) to program the axp221 dldo4 at, set to 0 to 35 disable dldo4. 36 37config AXP221_ALDO1_VOLT 38 int "axp221 aldo1 voltage" 39 depends on AXP221_POWER 40 default 0 41 ---help--- 42 Set the voltage (mV) to program the axp221 aldo1 at, set to 0 to 43 disable aldo1. On sun6i (A31) boards which have a wifi module this is 44 often used to power the wifi module. 45 46config AXP221_ALDO2_VOLT 47 int "axp221 aldo2 voltage" 48 depends on AXP221_POWER 49 default 0 if MACH_SUN6I 50 default 2500 if MACH_SUN8I 51 ---help--- 52 Set the voltage (mV) to program the axp221 aldo2 at, set to 0 to 53 disable aldo2. On sun6i (A31) boards this is typically unused and 54 should be disabled, if it is used for LPDDR2 it should be set to 1.8V. 55 On sun8i (A23) this is typically connected to VDD-DLL and must be set 56 to 2.5V. 57 58config AXP221_ALDO3_VOLT 59 int "axp221 aldo3 voltage" 60 depends on AXP221_POWER 61 default 3000 62 ---help--- 63 Set the voltage (mV) to program the axp221 aldo3 at, set to 0 to 64 disable aldo3. This is typically connected to VCC-PLL and AVCC and 65 must be set to 3V. 66 67config AXP221_ELDO3_VOLT 68 int "axp221 eldo3 voltage" 69 depends on AXP221_POWER 70 default 0 71 ---help--- 72 Set the voltage (mV) to program the axp221 eldo3 at, set to 0 to 73 disable eldo3. On some A31(s) tablets it might be used to supply 74 1.2V for the SSD2828 chip (converter of parallel LCD interface 75 into MIPI DSI). 76
