I am read


I use kernel xcomm_zynq_3_10


In configuration kernel I don't find:


Linux Kernel Configuration

Device Drivers  --->

<*>     Industrial I/O support --->

--- Industrial I/O support

-*-   Enable ring buffer support within IIO

-*-     Industrial I/O lock free software ring

-*-   Enable triggered sampling support


*** Analog to digital converters ***



<*>   Analog Devices AD9467 AD9643 High-Speed AXI ADC driver




Then when I load kernel:

Catalog /sys/bus/iio/devices/  is empty!!!


The main questions is:


1. What kernel version correctly for my platform(ZYNQ-7000 EPP 7Z020 ZedBoard) ?


2. How can I correctly edit devicetree.dts
