It has two numbers, 41*6be33864SEmmanuel Vadot the first number is the output resistor, the second number is the total 42*6be33864SEmmanuel Vadot resistance. Therefore, the adjusted vout is equal to 43*6be33864SEmmanuel Vadot Vout = Vout * output_resistance / total resistance. 44*6be33864SEmmanuel Vadot $ref: /schemas/types.yaml#/definitions/uint32-array 45*6be33864SEmmanuel Vadot minItems: 2 46*6be33864SEmmanuel Vadot maxItems: 2 47*6be33864SEmmanuel Vadot 48*6be33864SEmmanuel Vadotrequired: 49*6be33864SEmmanuel Vadot - compatible 50*6be33864SEmmanuel Vadot - reg 51*6be33864SEmmanuel Vadot 52*6be33864SEmmanuel VadotadditionalProperties: false 53*6be33864SEmmanuel Vadot 54*6be33864SEmmanuel Vadotexamples: 55*6be33864SEmmanuel Vadot - | 56*6be33864SEmmanuel Vadot i2c { 57*6be33864SEmmanuel Vadot #address-cells = <1>; 58*6be33864SEmmanuel Vadot #size-cells = <0>; 59*6be33864SEmmanuel Vadot 60*6be33864SEmmanuel Vadot max20730@10 { 61*6be33864SEmmanuel Vadot compatible = "maxim,max20730"; 62*6be33864SEmmanuel Vadot reg = <0x10>; 63*6be33864SEmmanuel Vadot vout-voltage-divider = <1000 2000>; // vout would be scaled to 0.5 64*6be33864SEmmanuel Vadot }; 65*6be33864SEmmanuel Vadot }; 66
