+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,adis16490"
+ * "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.
+- clocks: phandle to the external clock. Should be set according to
+ "clock-names".
+ If this field is left empty together with the "clock-names" field, then
+ the internal clock is used.
+- clock-names: The name of the external clock to be used. Valid values are:
+ * sync: In sync mode, the internal clock is disabled and the frequency
+ of the external clock signal establishes therate of data
+ collection and processing. See Fig 14 and 15 in the datasheet.
+ The clock-frequency must be:
+ * 3000 to 4500 Hz for adis1649x devices.
+ * 700 to 2400 Hz for adis1648x devices.
+ * pps: In Pulse Per Second (PPS) Mode, the rate of data collection and
+ production is equal to the product of the external clock
+ frequency and the scale factor in the SYNC_SCALE register, see
+ Table 154 in the datasheet.
+ The clock-frequency must be:
+ * 1 to 128 Hz for adis1649x devices.
+ * This mode is not supported by adis1648x devices.
+ If this field is left empty together with the "clocks" field, then the
+ internal clock is used.
+- adi,ext-clk-pin: The DIOx line to be used as an external clock input.
+ Valid values are:
+ * DIO1
+ * DIO2
+ * DIO3
+ * DIO4
+ Each DIOx pin supports only one function at a time (data ready line
+ selection or external clock input). When a single pin has two
+ two assignments, the enable bit for the lower priority function
+ automatically resets to zero (disabling the lower priority function).
+ Data ready has highest priority.
+ If this field is left empty, DIO2 is assigned as default external clock
+ input pin.
+
+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";
+ clocks = <&adis16495_sync>;
+ clock-names = "sync";
+ adi,ext-clk-pin = "DIO1";
+ };

+- drive-open-drain: the interrupt/data ready line will be configured
+ as open drain, which is useful if several sensors share the same
+ interrupt line. This is a boolean property.
+ (This binding is taken from pinctrl/pinctrl-bindings.txt)
+ If the requested interrupt is configured as IRQ_TYPE_LEVEL_HIGH or
+ IRQ_TYPE_EDGE_RISING a pull-down resistor is needed to drive the line
+ when it is not active, whereas a pull-up one is needed when interrupt
+ line is configured as IRQ_TYPE_LEVEL_LOW or IRQ_TYPE_EDGE_FALLING.
+- interrupts: interrupt mapping for IRQ. It should be configured with
+ flags IRQ_TYPE_LEVEL_HIGH, IRQ_TYPE_EDGE_RISING, IRQ_TYPE_LEVEL_LOW or
+ IRQ_TYPE_EDGE_FALLING.
+- wakeup-source: Enables wake up of host system on event.
+
+ Refer to interrupt-controller/interrupts.txt for generic interrupt
+ client node bindings.
+
+Example:
+
+lsm6dsm@6b {
+ compatible = "st,lsm6dsm";
+ reg = <0x6b>;
+ interrupt-parent = <&gpio0>;
+ interrupts = <0 IRQ_TYPE_EDGE_RISING>;
+};
