# AXP192 power management IC
|
|
|
|
A driver for the X-Powers `AXP192` PMIC: DCDC1-3/LDO2-3/EXTEN rail enable and voltage
|
|
control, battery voltage/current/power readback, charge enable/status, and system power off.
|
|
Registers as a `power-supply` child device (voltage, current, is-charging, charge control,
|
|
power off) alongside its own public API for full rail control.
|
|
|
|
Also includes `axp192-backlight`: a `BACKLIGHT_TYPE` driver for a backlight wired to one of
|
|
the AXP192's rails, declared as a devicetree child node of the `axp192` device it dims. Its
|
|
`rail`, `min-millivolt` and `max-millivolt` properties select the channel and map the 0-255
|
|
brightness level onto that rail's voltage range; brightness level 0 disables the rail outright.
