+Analog Devices AD5758 DAC device driver
+
+Required properties for the AD5758:
+ - compatible: Must be "adi,ad5758"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: Max SPI frequency to use (< 5000)
+ - spi-cpha: is the only mode that is supported
+
+Optional properties:
+
+ - adi,dc-dc-mode: Mode of operation of the dc-to-dc converter
+ The following values are currently supported:
+ * 0: DC-to-DC converter powered off
+ * 1: DPC current mode
+ * 2: DPC voltage mode
+ * 3: PPC current mode
+
+ - adi,dc-dc-ilim: The dc-to-dc converter current limit
+ The following values are currently supported [mA]:
+ * 150
+ * 200
+ * 250
+ * 300
+ * 350
+ * 400
+
+ - adi,slew: Array of slewrate settings should contain 3 fields:
+ 1: Should be either 0 or 1 in order to enable or disable slewrate.
+ 2: Slew rate clock:
+ Valid values for the slew rate update frequency [Hz]:
+ * 24
+ * 20
+ * 15
+ * 128000
+ * 64000
+ * 32000
+ * 16000
+ * 8000
+ * 4000
+ * 2000
+ * 1000
+ * 512
+ * 256
+ * 128
+ * 64
+ * 16
+ 3: Slew rate step:
+ Defines by how much the output value changes at each update.
+ Valid values for the step size LSBs:
+ * 4
+ * 12
+ * 64
+ * 120
+ * 256
+ * 500
+ * 1820
+ * 2048
+
+ - adi,range: The output range
+ The following values are currently supported:
+ * 0: 0 V to 5 V voltage range
+ * 1: 0 V to 10 V voltage range
+ * 2: ±5 V voltage range
+ * 3: ±10 V voltage range
+ * 8: 0 mA to 20 mA current range
+ * 9: 0 mA to 24 mA current range
+ * 10: 4 mA to 20 mA current range
+ * 11: ±20 mA current range
+ * 12: ±24 mA current range
+ * 13: −1 mA to +22 mA current range
+
+AD5758 Example:
+
+ ad5758@0 {
+ compatible = "adi,ad5758";
+ reg = <0>;
+ spi-max-frequency = <100>;
+ spi-cpha;
+
+ adi,dc-dc-mode = <2>;
+ adi,dc-dc-ilim = <200>;
+ adi,slew = <1 20 12>;
+ adi,range = <1>;
