We got a look at this issue with Yannick.

On my side, i got this problem because i used the 
stm32f746-disco_defconfig by updating CONFIG_DEFAULT_DEVICE_TREE with 
the following update, (and i suppose you do the same ;-) ):

CONFIG_DEFAULT_DEVICE_TREE="stm32f769-disco"

By using the stm32f769-disco_defconfig, everything is working fine.
That's why Yannick added a dedicated defconfig file for STM32F769.
