I am trying to get the analog inputs working on the AM3352.
In the Linux kernel, I have enabled the following:
Device Drivers ---
[*] Industrial I/O support --->
[*] Enable buffer support within IIO
<*> IIO callback buffer used for push in-kernel interfaces
< > Industrial I/O buffering based on kfifo
-*- Enable triggered sampling support
(2) Maximum number of consumers per trigger
Analog to digital converters --->
<*> TI's ADC driver
In the device tree, I have got
tscadc: tscadc@44e0d000{
status = "okay";
adc {
ti,adc-channels = <0 1 2 3 4 5 7>;
};
};
And I do have the sevent channels showing up under iio:device0:
root@LiteOn-SMC:~# ls -al /sys/bus/iio/devices/iio\:device0/

lrwxrwxrwx 1 root root 0 Mar 17 15:25 subsystem -> ../../../../../bus/iio
-rw-r--r-- 1 root root 4096 Mar 17 15:25 uevent
However, mode, buffer and scan_elements are missing. How do I set the ADC to continuous mode?
Any help are greatly appreciated.
