-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;
-	};
