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".
- fsl,pmic-stby-poweroff: if present, configure the PMIC to shutdown all
power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
Use this option if the SoC should be powered off by external power
management IC (PMIC) on PMIC_STBY_REQ signal.
As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
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.
