When referencing other schema, it is preferred to use an absolute path (/schemas/....), which allows also an seamless move of particular schema out of Linux kernel to dtschema.

BD71815AGW is a single-chip power management ICs for battery-powered
|
|
portable devices. It integrates 5 buck converters, 8 LDOs, a boost driver
|
|
for LED and a 500 mA single-cell linear charger. Also included is a Coulomb
|
|
counter, a real-time clock (RTC), and a 32.768 kHz clock gate and two GPOs.

BD71827 and BD71828 have SAR ADC for measuring charging currents.
|
|
External sense resistor (RSENSE in data sheet) should be used. If

something other but 30MOhm resistor is used the resistance value
|
|
should be given here in Ohms.

Usage of BD71828 GPIO pins can be changed via OTP. This property can be
|
|
used to mark the pins which should not be configured for GPIO. Please see

|
the ../gpio/gpio.txt for more information.

The BD71815 has undocumented GPO at pin E5. Pin is marked as GND at the
|
|
data-sheet as its location in the middle of GND pins makes it hard to
|
|
use on PCB. If your board has managed to use this pin you can enable the
|
|
second GPO by defining this property. Dont enable this if you are unsure
|
|
about how the E5 pin is connected on your board.
