+Analog Devices ADIS16480 and similar IMUs
+
+Required properties for the ADIS16480:
+
+- compatible: Must be one of
+ * "adi,adis16375"
+ * "adi,adis16480"
+ * "adi,adis16485"
+ * "adi,adis16488"
+ * "adi,adis16495-1"
+ * "adi,adis16495-2"
+ * "adi,adis16495-3"
+ * "adi,adis16497-1"
+ * "adi,adis16497-2"
+ * "adi,adis16497-3"
+- reg: SPI chip select number for the device
+- spi-max-frequency: Max SPI frequency to use
+ see: Documentation/devicetree/bindings/spi/spi-bus.txt
+- spi-cpha: See Documentation/devicetree/bindings/spi/spi-bus.txt
+- spi-cpol: See Documentation/devicetree/bindings/spi/spi-bus.txt
+- interrupts: interrupt mapping for IRQ, accepted values are:
+ * IRQF_TRIGGER_RISING
+ * IRQF_TRIGGER_FALLING
+
+Optional properties:
+
+- interrupt-names: Data ready line selection. Valid values are:
+ * DIO1
+ * DIO2
+ * DIO3
+ * DIO4
+ If this field is left empty, DIO1 is assigned as default data ready
+ signal.
+- reset-gpios: must be the device tree identifier of the RESET pin. As the line
+ is active low, it should be marked GPIO_ACTIVE_LOW.
+
+Example:
+
+ imu@0 {
+ compatible = "adi,adis16495-1";
+ reg = <0>;
+ spi-max-frequency = <3200000>;
+ spi-cpol;
+ spi-cpha;
+ interrupts = <25 IRQF_TRIGGER_FALLING>;
+ interrupt-parent = <&gpio>;
+ interrupt-names = "DIO2";
+ };
