+Analog Devices AD5064 DAC device driver
+
+Required properties:
+ - compatible: Must be one of:
+ * "adi,ad5024"
+ * "adi,ad5025"
+ * "adi,ad5044"
+ * "adi,ad5045"
+ * "adi,ad5064"
+ * "adi,ad5064-1"
+ * "adi,ad5065"
+ * "adi,ad5628-1"
+ * "adi,ad5628-2"
+ * "adi,ad5648-1"
+ * "adi,ad5648-2"
+ * "adi,ad5666-1"
+ * "adi,ad5666-2"
+ * "adi,ad5668-1"
+ * "adi,ad5668-2"
+ * "adi,ad5668-3"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: Max SPI frequency to use (< 30000000)
+ - vrefA-supply, vrefB-supply: phandles to external reference voltage
+ supplies for channels 0 and 1 respectively.
+ This property must be present for ad5024, ad5025, ad5044, ad5045,
+ ad5064, ad5065.
+ - vrefC-supply, vrefD-supply: phandles to external reference voltage
+ supplies for channels 2 and 3 respectively.
+ This property must be present for ad5024, ad5044, ad5064.
+
+Optional properties:
+ - vref-supply: phandle to the external reference voltage supply.
+ This should only be set if there is an external reference voltage
+ connected to the vref or vref[A-D] pins.
+ If the property is not set, the internal reference voltage supply
+ is used if present.
+ This property can be used with ad5064-1, ad5628-1, ad5628-2, ad5648-1,
+ ad5648-2, ad5666-1, ad5666-2, ad5668-1, ad5668-2, ad5668-3.
+
+Example:
+
+ ad5668-2@4 {
+ compatible = "adi,ad5668-2";
+ reg = <4>;
+ spi-max-frequency = <10000000>;
+ adi,use-external-reference;
+ vref-supply = <&vref_supply>;
+ };
