hanks for reply. Based on following:

https://github.com/Xilinx/linux-xlnx/blob/master/Documentation/devicetree/bindings/hwmon/lm70.txt

Where should I put following? at system-user.dtsi?

spi_master {

temperature-sensor@0 {

compatible = "ti,lm70";

reg = <0>;

spi-max-frequency = <1000000>;

};

};

Also lm70.c is xilinx kernel driver, I need create an module on my own like your said?

Thanks
