See 57 comments below for bucks/LDOs which support this. 0 means 58 regulator should be disabled at RUN state. 59 $ref: /schemas/types.yaml#/definitions/uint32 60 minimum: 0 61 maximum: 3300000 62 63 rohm,dvs-snvs-voltage: 64 description: 65 Whether to keep regulator enabled at "SNVS" state or not. 66 0 means regulator should be disabled at SNVS state, non zero voltage 67 keeps regulator enabled. BD71815 does not change voltage level 68 when PMIC transitions to SNVS.SNVS voltage depends on the previous 69 state (from which the PMIC transitioned to SNVS). 70 $ref: /schemas/types.yaml#/definitions/uint32 71 minimum: 0 72 maximum: 3300000 73 74 rohm,dvs-suspend-voltage: 75 description: 76 PMIC "SUSPEND" state voltage in uV when PMIC HW states are used. See 77 comments below for bucks/LDOs which support this. 0 means 78 regulator should be disabled at SUSPEND state. 79 $ref: /schemas/types.yaml#/definitions/uint32 80 minimum: 0 81 maximum: 3300000 82 83 rohm,dvs-lpsr-voltage: 84 description: 85 PMIC "LPSR" state voltage in uV when PMIC HW states are used.

The voltage is automatically changed when HW 95 # state changes. Omitting these properties from bucks 1 and 2 leave 96 # buck voltages to not be toggled by HW state. Enable status may still 97 # be toggled by state changes depending on HW default settings. 98 # 99 # Bucks 3-5 and ldos 1-5 support setting the RUN state voltage here. 100 # Given RUN voltage is used at all states if regulator is enabled at 101 # given state. 102 # Values given for other states are regarded as enable/disable at 103 # given state (see below). 104 # 105 # All regulators except WLED support specifying enable/disable status 106 # for each of the HW states (RUN/SNVS/SUSPEND/LPSR). HW defaults can 107 # be overridden by setting voltage to 0 (regulator disabled at given 108 # state) or non-zero (regulator enabled at given state). Please note 109 # that setting non zero voltages for bucks 1/2 will also enable voltage 110 # changes according to state change. 111 112 required: 113 - regulator-name 114 115 unevaluatedProperties: false 116 117 additionalProperties: false
