| 14 | This is a part of device tree bindings for Maxim MAX77802 Power Management |
| 15 | Integrated Circuit (PMIC). |
| 16 | |
| 17 | The Maxim MAX77686 provides 10 high-efficiency Buck and 32 Low-DropOut (LDO) |
| 18 | regulators. |
| 19 | |
| 20 | See also Documentation/devicetree/bindings/mfd/maxim,max77802.yaml for |
| 21 | additional information and example. |
| 22 | |
| 23 | Certain regulators support "regulator-initial-mode" and "regulator-mode". |
| 24 | The valid modes list is defined in the dt-bindings/regulator/maxim,max77802.h |
| 25 | and their meaning is:: |
| 26 | 1 - Normal regulator voltage output mode. |
| 27 | 3 - Low Power which reduces the quiescent current down to only 1uA |
| 28 | |
| 29 | The standard "regulator-mode" property can only be used for regulators that |
| 30 | support changing their mode to Low Power Mode during suspend. These |
| 31 | regulators are:: bucks 2-4 and LDOs 1-35. Also, it only takes effect if the |
| 32 | regulator has been enabled for the given suspend state using |
| 33 | "regulator-on-in-suspend" and has not been disabled for that state using |
| 34 | "regulator-off-in-suspend". |
