-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:
-	- #address-cells: Should be 1.
-	- #size-cells: Should be 0.
-	- channel nodes:
-	  Each child node represents one channel and has the following
-	  Required properties:
-		* reg: Pin on which this channel is connected to.
-		* adi,mode: Mode or function of this 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 unused)
-				* CH_MODE_ADC (the pin is ADC input)
-				* CH_MODE_DAC (the pin is DAC output)
-				* CH_MODE_DAC_AND_ADC (the pin is DAC output
-					but can be monitored by an ADC, since
-					there is no disadvantage this
-					this should be considered as the
-					preferred DAC mode)
-				* CH_MODE_GPIO (the pin is registered
-					with GPIOLIB)
-	 Optional properties:
-		* adi,off-state: State of this channel when unused or the
-				 device gets removed. Macros specifying the
-				 valid values can be found in
-				 <dt-bindings/iio/adi,ad5592r.h>.
-
-				* CH_OFFSTATE_PULLDOWN (the pin is pulled down)
-				* CH_OFFSTATE_OUT_LOW  (the pin is output low)
-				* CH_OFFSTATE_OUT_HIGH (the pin is output high)
-				* CH_OFFSTATE_OUT_TRISTATE (the pin is
-					tristated output)
-
-
-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
-	  pin. If the property is not set the internal 2.5V reference is used.
-	- reset-gpios : GPIO spec for the RESET pin. If specified, it will be
-	  asserted during driver probe.
-	- gpio-controller: Marks the device node as a GPIO controller.
-	- #gpio-cells: Should be 2. The first cell is the GPIO number and the second
-	  cell specifies GPIO flags, as defined in <dt-bindings/gpio/gpio.h>.
