Hi Anand,
It's an old problem and we have identified its root cause a long time ago:
https://lists.denx.de/pipermail/u-boot/2015-October/231061.html
Basically, a voltage regulator is not getting initialized because a call to the board_usb_init() function was lost during the DM conversion. You can try to compile U-Boot from my branch, it contains the rebased fixes which I have been using all this time on my ODROID-X board:
https://github.com/ssvb/u-boot/commits/20170306-unbreak-odroid
I did all the initial investigation back in 2015, but tried to delegate the actual bugfixing work to the ODROID board maintainer(s). Apparently it did not fly and ODROID support is still broken.
If you can test my branch and confirm that it works on your ODROID-U3, then I can maybe spend some time on making cleaner patches and ensuring that they reach the U-Boot git repository.
Thanks!
