It is interfaced using an I2C interface. Each sub-block is 16 addressed by the host system using different i2c slave address. 17 18properties: 19 compatible: 20 enum: 21 - maxim,max8998 22 - national,lp3974 23 - ti,lp3974 24 25 reg: 26 maxItems: 1 27 28 interrupts: 29 minItems: 1 30 items: 31 - description: Main interrupt 32 - description: Power-on/-off interrupt 33 34 max8998,pmic-buck1-dvs-gpios: 35 maxItems: 2 36 description: 37 Two host gpios used for buck1 DVS. 38 39 max8998,pmic-buck2-dvs-gpio: 40 maxItems: 1 41 description: 42 Host gpio used for buck2 DVS. 43 44 max8998,pmic-buck1-default-dvs-idx: 45 $ref: /schemas/types.yaml#/definitions/uint32 46 enum: [0, 1, 2, 3] 47 default: 0 48 description: 49 Default voltage setting selected from the possible 4 options selectable 50 by the DVS gpios. 51 52 max8998,pmic-buck2-default-dvs-idx: 53 $ref: /schemas/types.yaml#/definitions/uint32 54 enum: [0, 1] 55 default: 0 56 description: 57 Default voltage setting selected from the possible 2 options selectable 58 by the DVS GPIOs. 59 60 max8998,pmic-buck-voltage-lock: 61 type: boolean 62 description: 63 If present, disallows changing of preprogrammed buck DVS voltages. 64 65 max8998,pmic-buck1-dvs-voltage: 66 $ref: /schemas/types.yaml#/definitions/uint32-array 67 maxItems: 4 68 description: 69 Four voltage values in microvolts for buck1 regulator that can be 70 selected using DVS GPIO. 71 72 max8998,pmic-buck2-dvs-voltage: 73 $ref: /schemas/types.yaml#/definitions/uint32-array 74 maxItems: 2 75 description: 76 Two voltage values in microvolts for buck2 regulator that can be 77 selected using DVS GPIO. 78 79 regulators: 80 type: object 81 additionalProperties: false 82 83 properties: 84 CHARGER: 85 type: object 86 $ref: /schemas/regulator/regulator.yaml# 87 unevaluatedProperties: false 88 description: 89 CHARGER is main battery charger current control, wrongly represented 90 as regulator. 91 92 properties: 93 regulator-min-microamp: 94 minimum: 90000 95 maximum: 800000 96 97 regulator-max-microamp: 98 minimum: 90000 99 maximum: 800000 100 101 regulator-min-microvolt: false 102 regulator-max-microvolt: false 103 104 required: 105 - regulator-name 106 107 patternProperties: 108 "^(LDO([2-9]|1[0-7])|BUCK[1-4])$": 109 type: object 110 $ref: /schemas/regulator/regulator.yaml# 111 unevaluatedProperties: false 112 113 required: 114 - regulator-name 115 116 "^(EN32KHz-AP|EN32KHz-CP|ENVICHG|ESAFEOUT[12])$": 117 type: object 118 $ref: /schemas/regulator/regulator.yaml# 119 unevaluatedProperties: false 120 description: | 121 EN32KHz-AP and EN32KHz-CP are 32768 Hz clocks, wrongly represented as 122 regulators. 123 ENVICHG is a Battery Charging Current Monitor Output. 124 125 properties: 126 regulator-min-microvolt: false 127 regulator-max-microvolt: false 128 129 required: 130 - regulator-name 131 132dependencies: 133 max8998,pmic-buck1-dvs-gpios: [ "max8998,pmic-buck1-dvs-voltage" ] 134 max8998,pmic-buck2-dvs-gpio: [ "max8998,pmic-buck2-dvs-voltage" ] 135 136required: 137 - compatible 138 - reg 139 - regulators 140 141additionalProperties: false 142 143examples: 144 - | 145 #include <dt-bindings/gpio/gpio.h> 146 #include <dt-bindings/interrupt-controller/irq.h> 147 148 i2c { 149 #address-cells = <1>;
