| 58 | Optional properties: |
| 59 | - Any optional property defined in bindings/regulator/regulator.txt |
| 60 | For twl4030 regulators/LDOs: |
| 61 | - regulator-initial-mode: |
| 62 | - 0x08 - Sleep mode, the nominal output voltage is maintained with low power |
| 63 | consumption with low load current capability. |
| 64 | - 0x0e - Active mode, the regulator can deliver its nominal output voltage |
| 65 | with full-load current capability. |
| 66 | |
| 67 | Example: |
| 68 | |
| 69 | xyz: regulator@0 { |
| 70 | compatible = "ti,twl6030-vaux1"; |
| 71 | regulator-min-microvolt = <1000000>; |
| 72 | regulator-max-microvolt = <3000000>; |
| 73 | }; |
| 74 | |
| 75 | For twl6030 regulators/LDOs: |
| 76 | |
| 77 | - ti,retain-on-reset: Does not turn off the supplies during warm |
| 78 | reset. Could be needed for VMMC, as TWL6030 |
| 79 | reset sequence for this signal does not comply |
| 80 | with the SD specification. |
