* ROHM BD71837 and BD71847 Power Management Integrated Circuit bindings
|
|
|
|
BD71837MWV and BD71847MWV are programmable Power Management ICs for powering
|
|
single-core, dual-core, and quad-core SoCs such as NXP-i.MX 8M. They are
|
|
optimized for low BOM cost and compact solution footprint. BD71837MWV
|
|
integrates 8 Buck regulators and 7 LDOs. BD71847MWV contains 6 Buck regulators
|
|
and 6 LDOs.
|
|
|
|
Datasheet for BD71837 is available at:
|
|
https://www.rohm.com/datasheet/BD71837MWV/bd71837mwv-e
|
|
|
|
Required properties:
|
|
- compatible : Should be "rohm,bd71837" for bd71837
|
|
"rohm,bd71847" for bd71847.
|
|
- reg : I2C slave address.
|
|
- interrupt-parent : Phandle to the parent interrupt controller.
|
|
- interrupts : The interrupt line the device is connected to.
|
|
- clocks : The parent clock connected to PMIC. If this is missing
|
|
32768 KHz clock is assumed.
|
|
- #clock-cells : Should be 0.
|
|
- regulators: : List of child nodes that specify the regulators.
|
|
Please see ../regulator/rohm,bd71837-regulator.txt
|
|
|
|
Optional properties:
|
|
- clock-output-names : Should contain name for output clock.
