Binding for Maxim MAX20010 regulator
MAX20010 is a synchronous step-down converter. It is able to deliver upto 6A
with 2 different programmable output voltages from 0.5V to 1.27V in 10mV steps
and from 0.625V to 1.5875V in 12.5mV steps. It supports synchronous
rectification and automatic PWM/PFM transitions.
The MAX20010 interface is via I2C bus.
=======================
Supported Properties
=======================
- compatible
Usage: required
Value type: <string>
Definition: should be "maxim,max20010".
- reg
Usage: required
Value type: <u32>
Definition: The device 8-bit I2C address.
- vin-supply
Usage: optional
Value type: <phandle>
Definition: This is the phandle for the parent regulator. Typically used
for EN pin control of the buck.
- regulator-initial-mode
Usage: optional
Value type: <u32>
Definition: The regulator operating mode. Should be either
"MAX20010_OPMODE_SYNC" or "MAX20010_OPMODE_FPWM".
These constants are defined in file
include/dt-bindings/regulator/max20010.h
- maxim,vrange-sel
Usage: optional
Value type: <u32>
Definition: Integer value specifies the voltage range to be used.
Supported values are 0 or 1.
Value 0 supports voltage range from 0.5V to 1.27V in 10mV
steps. Value 1 supports voltage range from 0.625V to 1.5875V
in 12.5mV steps.
- maxim,soft-start-slew-rate
Usage: optional
Value type: <u32>
Definition: An integer value specifies the slew rate in uV/uS to be used
for soft-start operation of the buck. Supported values are
5500, 11000, 22000 and 44000.
- maxim,dvs-slew-rate
Usage: optional
Value type: <u32>
Definition: An integer value specifies the slew rate in uV/uS to be used
for buck dynamic voltage scaling operations. Supported
values are 5500, 11000, 22000 and 44000.
