The xilinx-xadc IIO driver currently has support for the XADC in
the Xilinx
7 series FPGAs. The system-monitor is the equivalent to the XADC in
the Xilinx UltraScale and UltraScale+ FPGAs.
The IP designers did a good job at maintaining backwards
compatibility and only minor changes are required to add basic
support for the system-monitor core.
The non backwards compatible changes are:
* Register map offset was moved from 0x200 to 0x400
* Only one ADC compared to two in the XADC
* 10 bit ADC instead of 12 bit ADC
* Two of the channels monitor different supplies
Add the necessary logic to accommodate these changes to support the
system-monitor in the XADC driver.
Note that this patch does not include support for some new features
found in the system-monitor like additional alarms, user supply
monitoring and secondary system-monitor access. This might be added
at a later time.

Very nice. Will let this sit on the mailing list a bit longer but
looks good to me.
FYI: I have asked Anand to take a look at it and retest.
Thanks,
Michal
Hi Michal / Anand,
Any feedback on this one?
Thanks
Jonathan
p.s. I'm just ploughing through my older emails and had this one marked as
waiting for a reply.
Hi Jonathan,
Thanks for waiting.
The patch looks good.

Thanks. I've applied this but there was a bit of complexity around
devm changes that went in whilst this was under review.
I think I fixed it up correctly, but great if you can take
a quick look to make sure I didn't mess it up.
I'll try and put the other outstanding series in as well which
will probably result in more fiddly corners during the merge.
Applied to the togreg branch of iio.git and pushed out as testing
or the autobuilders to see what we missed.
Thanks Johnathan.
I'm not seeing the patches in your public repository yet :)
