Microchip mcp4725 and mcp4726 DAC device driver Required properties: - compatible: Must be "microchip,mcp4725" or "microchip,mcp4726" - reg: Should contain the DAC I2C address - vdd-supply: Phandle to the Vdd power supply. This supply is used as a voltage reference on mcp4725. It is used as a voltage reference on mcp4726 if there is no vref-supply specified. Optional properties (valid only for mcp4726): - vref-supply: Optional phandle to the Vref power supply. Vref pin is used as a voltage reference when this supply is specified. - microchip,vref-buffered: Boolean to enable buffering of the external Vref pin. This boolean is not valid without the vref-supply. Quoting the datasheet: This is offered in cases where the reference voltage does not have the current capability not to drop its voltage when connected to the internal resistor ladder circuit. Examples: /* simple mcp4725 */ mcp4725@60 { compatible = "microchip,mcp4725"; reg = <0x60>; vdd-supply = <&vdac_vdd>; }; /* mcp4726 with the buffered external reference voltage */ mcp4726@60 { compatible = "microchip,mcp4726"; reg = <0x60>; vdd-supply = <&vdac_vdd>; vref-supply = <&vdac_vref>; microchip,vref-buffered; };
