The valid names for regulators are: |

--PFUZE100 |
|
sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6 |
|

--PFUZE3001 |
|
sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4 |

Each regulator is defined using the standard binding for regulators. |

description: | |
|
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 regulators 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: |
|
$ref: /schemas/types.yaml#/definitions/flag |
|
description: | |
|
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. |
