Device tree overlays and kernel versions

I am considering moving from RCN kernel 3.8.13-bone35.1 to 3.13.0-rc7 to take advantage of some USB updates. It appears that device tree overlays are not yet supported in the latter. My questions are:

1) Are my observations correct?
2) If this is true, then are device tree overlays being dropped in later kernel versions?

Best regards,

Dave.

"dropped" is really the wrong word to use...

NO ONE has taken up the effort to fully port the 3.8 "overlays" to 3.13...

Personally, i'm working on a workaround that works for me and for most
cape users.

I'm just guessing, but the guy who originally wrote the 3.8 overlay
system would probably take cash in trade to keep working on it..

Thanks Robert. I was thinking of a workaround also, but did not want to "reinvent a wheel". Could you point me to your thoughts? It seems to me that the major issue is setting up the pinmux and associated resource allocation.

When/if I have cash - I'll keep this in mind :wink:

Thanks for the new kernel work.

I also tried 3.13-rc7 (using linux-dev scripts) for better USB, but also for the newer iio subsystem for continuous sampling of ADCs
(see http://beagleboard-gsoc13.blogspot.co.at/2013/09/success-at-last.html?showComment=1386797252321#c4667539797894788582 )

Now I get ADC iio:device0 activated but only with 3 channels,

ls /sys/bus/iio/devices/iio:device0/
buffer dev in_voltage4_raw in_voltage5_raw in_voltage6_raw name power scan_elements subsystem uevent

Can you give my some hints:
Where are these settings done, where can I change them ?

best regards
