Release 4.11 drivers/mfd/axp20x-rsb.c
/*
* RSB driver for the X-Powers' Power Management ICs
*
* AXP20x typically comprises an adaptive USB-Compatible PWM charger, BUCK DC-DC
* converters, LDOs, multiple 12-bit ADCs of voltage, current and temperature
* as well as configurable GPIOs.
*
* This driver supports the RSB variants.
