I wrote earlier about my problems getting USB going with a DVEVM-alike board.
I diagnosed into 'board-dm644x-evm.c', to find out why the device is not registered and the outcome for now is that 'evm_u35_setup' which finally does 'setup_usb' is not called. Unfortunately, the 'alike' board differs here, in that it does not have a GPIO, which might explain the different behavior of the system. On the board at hand, the USB power is hard-wired.
I'll get an original DVEVM board to harden this finding and report back as soon as i had seen the behavior of the driver on the original reference board, and would, if it will run as expected, then have the case to get a board running without GPIO at all.
As your discussion indicates, the gpio material (vbus) might then indeed be needed to be moved out of the way, to get the board at hand running USB. I'll also have the problem to find another hook to call 'setup_usb'.
Just stop abusing board-dm644x-evm.c since your board is different and that file is only intended to support DM644x EVM.
Thanks again
