* 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 |
|
variant of ../interrupt-controller/interrupts.txt |
|
- gpio-controller : To indicate BD70528 acts as a GPIO controller. |
|
- #gpio-cells : Should be 2. The first cell is the pin number and |
|
the second cell is used to specify flags. See |
|
../gpio/gpio.txt for more information. |
|
- #clock-cells : Should be 0. |
|
- regulators: : List of child nodes that specify the regulators. |
|
Please see ../regulator/rohm,bd70528-regulator.txt |
|
|
|
Optional properties: |
|
- clock-output-names : Should contain name for output clock. |
|
|
