* ROHM BD70528 Power Management Integrated Circuit bindings
|
||||
|
||||
BD70528MWV is an ultra-low quiescent current general purpose, single-chip,
|
||||
power management IC for battery-powered portable devices. The IC
|
||||
integrates 3 ultra-low current consumption buck converters, 3 LDOs and 2
|
||||
LED Drivers. Also included are 4 GPIOs, a real-time clock (RTC), a 32kHz
|
||||
clock gate, high-accuracy VREF for use with an external ADC, flexible
|
||||
dual-input power path, 10 bit SAR ADC for battery temperature monitor and
|
||||
1S battery charger with scalable charge currents.
|
||||
|
||||
Required properties:
|
||||
- compatible : Should be "rohm,bd70528"
|
||||
- reg : I2C slave address.
|
||||
- interrupts : The interrupt line the device is connected to.
|
||||
- interrupt-controller : To indicate BD70528 acts as an interrupt controller.
|
||||
- #interrupt-cells : Should be 2. Usage is compliant to the 2 cells
