In many cases the states and 15 transitions are SOC specific, but ones described here can be found from a 16 few of the different ROHM PMICs. 17 18properties: 19 rohm,dvs-run-voltage: 20 description: 21 PMIC "RUN" state voltage in uV when PMIC HW states are used. 0 means the 22 regulator should be disabled at RUN state. Some regulators do not support 23 setting HW state specific voltage but do support enable/disable control. 24 For them any positive value means the regulator should be enabled without 25 touching the voltage. 26 $ref: /schemas/types.yaml#/definitions/uint32 27 28 rohm,dvs-suspend-voltage: 29 description: 30 PMIC "SUSPEND" state voltage in uV when PMIC HW states are used. 0 means 31 the regulator should be disabled at SUSPEND state. Some regulators do not 32 support setting HW state specific voltage but do support enable/disable 33 control. For them any positive value means the regulator should be 34 enabled without touching the voltage. 35 $ref: /schemas/types.yaml#/definitions/uint32 36 37 rohm,dvs-idle-voltage: 38 description: 39 PMIC "IDLE" state voltage in uV. 0 means the regulator should be disabled 40 at IDLE state. Some regulators do not support setting HW state specific 41 voltage but do support enable/disable control. For them any positive 42 value means the regulator should be enabled without touching the voltage. 43 $ref: /schemas/types.yaml#/definitions/uint32 44 45 rohm,dvs-lpsr-voltage: 46 description: 47 PMIC "LPSR" state voltage in uV when PMIC HW states are used. 0 means the 48 regulator should be disabled at LPSR state. Some regulators do not 49 support setting HW state specific voltage but do support enable/disable 50 control. For them any positive value means the regulator should be 51 enabled without touching the voltage. Some PMICs' documentation may refer 52 to this state as a "deep-idle state". 53 $ref: /schemas/types.yaml#/definitions/uint32 54 55# The schema is expected to be reference by PMIC schemas, which may introduce 56# other properties that must be allowed. 57additionalProperties: true 58
