hello.
I have already modified the rpi-ad5593r-overlay.dts file on the CM4 Board to suit my environment.
And I'm using the pyadi-io Module to use AD5593R.
MAX31865 (not MAX31856) also had a pyadi-iio example.

However, there was no dts file involved. Is there a way to use MAX31865 through linux iio driver?
Not sure I understand - there is a mainline IIO driver for MAX31865 here:

Do you know where the max31865 device tree is?
You can find an example here:
examples: - | spi { #address-cells = <1>; #size-cells = <0>; temperature-sensor@0 { compatible = "maxim,max31865"; reg = <0>; spi-max-frequency = <400000>; spi-cpha; maxim,3-wire; }; };
