MAXIM, MAX77686 regulators
|
||
|
|
|
||
|
|
This device uses two drivers:
|
||
|
|
- drivers/power/pmic/max77686.c (as parent I/O device)
|
||
|
|
- drivers/power/regulator/max77686.c (for child regulators)
|
||
|
|
|
||
|
|
This file describes the binding info for the REGULATOR driver.
|
||
|
|
|
||
|
|
First, please read the binding info for the pmic:
|
||
|
|
- doc/device-tree-bindings/pmic/max77686.txt
|
||
|
|
|
||
|
|
Required subnode:
|
||
|
|
- voltage-regulators: required for the PMIC driver
|
||
|
|
|
||
|
|
Required properties:
|
||
|
|
- regulator-name: used for regulator uclass platform data '.name'
|
||
|
|
|
||
|
|
Optional:
|
||
|
|
- regulator-min-microvolt: minimum allowed Voltage to set
|
||
|
|
- regulator-max-microvolt: minimum allowed Voltage to set
|
||
|
|
- regulator-always-on: regulator should be never disabled
|
||
|
|
- regulator-boot-on: regulator should be enabled by the bootloader
|
||
|
|
|
||
|
|

|
||
|
|
(subnode of max77686 pmic node)
