LTC2983 & Device Tree (ZynqMP Ultarscale+ ADRV9009-ZU11EG)


I'm looking to customize the device tree on my linux target to incorporate the LTC2983 temp sensor. I've been referencing SPI device initialization here and the device tree customization on the target here. Does incorporating this SPI device initialization example into a .dts file expose the LTC298 properties to the devicetree after a reboot? And if so what dts file does the initialization example need to be place in?

  • Hi Adrian,

    I'm working with Ryne on this program.  Are there any references to a Device Tree file for the ADRV9009-ZU11EG or similar Zynq system that uses two SPI interfaces?  The ADRV9009-ZU11EG only uses the SPI0 interface. We would like to use the SPI1 interface if possible and may avoid having to re-build the HDL code (Boot.bin file).  I see in the hardware schematics for the RFSOM that the SPI1 interface is mapped to P2.D19, P2.D20, ..., P2.D24 and associated with Processing System(PS) MIO19,MIO20,MIO21,MIO22,MIO23 and MIO18. 

    See this snippet of the RFSOM ADRV9009-ZU11EG schematic ...
