+Analog Devices AD5592R/AD5593R DAC/ADC device driver
+
+Required properties for the AD5592R:
+ - compatible: Must be "adi,ad5592r"
+ - reg: SPI chip select number for the device
+ - spi-max-frequency: Max SPI frequency to use (< 30000000)
+ - spi-cpol: The AD5592R requires inverse clock polarity (CPOL) mode
+
+Required properties for the AD5593R:
+ - compatible: Must be "adi,ad5593r"
+ - reg: I2C address of the device
+
+Required properties for all supported chips:
+ - channel-modes: An array of eight 8-bit values (one per channel)
+ describing the mode of each channel. Macros specifying the valid
values
+ can be found in <dt-bindings/iio/adi,ad5592r.h>.
+ The following values are currently supported:
+ * CH_MODE_UNUSED (the pin is pulled down)
+ * CH_MODE_DAC
+ * CH_MODE_ADC
+ * CH_MODE_GPIO_TRISTATE
+
+Example:
+
+ #include <dt-bindings/iio/adi,ad5592r.h>
+
+ ad5592r@0 {
+ compatible = "adi,ad5592r";
+ reg = <0>;
+ spi-max-frequency = <1000000>;
+ spi-cpol;
+
+ channel-modes = /bits/ 8 <
+ CH_MODE_DAC
+ CH_MODE_ADC
+ CH_MODE_ADC
+ CH_MODE_UNUSED
+ CH_MODE_UNUSED
+ CH_MODE_UNUSED
+ CH_MODE_UNUSED
+ CH_MODE_UNUSED>;
