"broken dt data from edma" message while booting linux-ti-staging-rt-4.1

Hi!

I have seen nightly builds of fido RT passing quite consistently. However,
I got nasty error messages while my am335x booted linux-ti-staging-rt-4.1
as follows:

[    0.146612] omap_hwmod: tptc0 using broken dt data from edma
[    0.146751] omap_hwmod: tptc1 using broken dt data from edma
[    0.146868] omap_hwmod: tptc2 using broken dt data from edma
[    0.151906] omap_hwmod: debugss: _wait_target_disable failed

Perhaps for this reason I also get:
Configuring network interfaces... ifconfig: SIOCGIFFLAGS: No such device

and

Failed to get index for interface name 'eth0': No such device

- so I don't get Ethernet up and running.

I have used Yocto version of meta-ti (fido).

I found
https://www.mail-archive.com/linux-omap@vger.kernel.org/msg116472.html
discussing this problem, but I did not these changes made in am33xx.dtsi.

What patches should I need to get rt-4.1 running properly?

Thanks,
Matti

Those " broken dt data" lines are not the problem. They seem to exist also
in normal 3.14 boot without problems. Two clear differences are: there is
no nand flash memory mapping and that there is that SIOCGIFFLAGS.

Perhaps I try normal 4.1 kernel also. I used to get it running before.

Problem was device tree.
4.1 seems to be more accurate with dtb parsing.
Status = okay  definitions were missing in Ethernet structures.

Matti,

Thank you for the update! Glad you were able to track it down.
