   1 config 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.

   9 config 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.

  19 config 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
  29 config 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
  37 config 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
  46 config 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
  58 config 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
  67 config 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).
