13   The valid names for regulators are:
14   --PFUZE100
15   sw1ab,sw1c,sw2,sw3a,sw3b,sw4,swbst,vsnvs,vrefddr,vgen1~vgen6
16   --PFUZE200
17   sw1ab,sw2,sw3a,sw3b,swbst,vsnvs,vrefddr,vgen1~vgen6,coin
18   --PFUZE3000
19   sw1a,sw1b,sw2,sw3,swbst,vsnvs,vrefddr,vldo1,vldo2,vccsd,v33,vldo3,vldo4
20   --PFUZE3001
21   sw1,sw2,sw3,vsnvs,vldo1,vldo2,vccsd,v33,vldo3,vldo4
23   Each regulator is defined using the standard binding for regulators.

41     description: |
42       Boolean, if present disable all unused switch regulators to save power
43       consumption. Attention, ensure that all important regulators
44       (e.g. DDR ref, DDR supply) has set the "regulator-always-on" property.
45       If not present, the switched regulators are always on and can't be
46       disabled. This binding is a workaround to keep backward compatibility
47       with old dtb's which rely on the fact that the switched regulators are
48       always on and don't mark them explicit as "regulator-always-on".
50   fsl,pmic-stby-poweroff:

52     description: |
53       if present, configure the PMIC to shutdown all
54       power rails when PMIC_STBY_REQ line is asserted during the power off sequence.
55       Use this option if the SoC should be powered off by external power management
56       IC (PMIC) on PMIC_STBY_REQ signal.
57       As opposite to PMIC_STBY_REQ boards can implement PMIC_ON_REQ signal.
