+Microchpip mcp4725 and mcp4726 DAC device driver
+
+Required properties:
+ - compatible: Must be "microchip,mcp4725" or "microchip,mcp4726"
+ - reg: Should contain the DAC I2C address
+ - vref-millivolt: Value of the reference voltage
+
+Optional properties:
+ - vref-mode: Reference voltage selection. It is available only on
+ mcp4726. Valid values are:
+ - 0, 1: Vdd pin voltage (unbuffered)
+ - 2: Vref pin voltage unbuffered
+ - 3: Vref pin voltage internally buffered
+
+Examples:
+
+ mcp4725@60 {
+ compatible = "microchip,mcp4725";
+ reg = <0x60>;
+ vref-millivolt = <3300>;
+ };
+
+ mcp4726@60 {
+ compatible = "microchip,mcp4726";
+ reg = <0x60>;
+ vref-mode = <2>;
+ vref-millivolt = <2500>;
+ };
