This binding is used to keep the backward compatibility with the current dtb's [1]. The binding informs the driver that the unused switch regulators can be disabled. If it is not specified, the driver doesn't disable the switch regulators.

PFUZE100 family of regulators
|
|
|
|
Required properties:
|
|
- compatible: "fsl,pfuze100", "fsl,pfuze200", "fsl,pfuze3000", "fsl,pfuze3001"
|
|
- reg: I2C slave address
|
|
|
|
Optional properties:
|
|
- fsl,pfuze-support-disable-sw: Boolean, if present disable all unused switch
|
|
regulators to save power consumption. Attention, ensure that all important
|
|
regulators (e.g. DDR ref, DDR supply) has set the "regulator-always-on"
|
|
property. If not present, the switched regualtors are always on and can't be
|
|
disabled. This binding is a workaround to keep backward compatibility with
|
|
old dtb's which rely on the fact that the switched regulators are always on
|
|
and don't mark them explicit as "regulator-always-on".
|
|
|
|
Required child node:
|
|
- regulators: This is the list of child nodes that specify the regulator
|
|
initialization data for defined regulators. Please refer to below doc
|
|
Documentation/devicetree/bindings/regulator/regulator.txt.
|
|
|
|
The valid names for regulators are:
|
|
--PFUZE100
|
|
sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
|
|
--PFUZE200
|
|
sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
|
|
--PFUZE3000
|
|
sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4
|
|
--PFUZE3001
|
|
sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4
|
|
|
|
Each regulator is defined using the standard binding for regulators.
