I want to configure adis16465 IMU in scaled sync mode. The external clock node is not specified in the official example,they just lists a label simply,as shown below ,so how should I edit the details of the label?
compatible = "adi,adis16495-1";
reg = <0>;
spi-max-frequency = <3200000>;
interrupts = <25 IRQF_TRIGGER_FALLING>;
interrupt-parent = <&gpio>;
interrupt-names = "DIO2";
clocks = <&adis16495_sync>;//just a label...
clock-names = "sync";
adi,ext-clk-pin = "DIO1";
Sorry for late response.
Please describe a bit your setup.
Also please have a look at the YAML devicetree bindings for this IMU chip. You'll see that for scaled sync mode your clock-names property should be "scaled-sync" and you should define another property called adi,scaled-output-hz and set it accordingly.
The label should, depending on your setup, point to a clock provider node or to a fixed clock.
