Let me answer to this in next comment.

hsi2c_5 and i2s_0 are not used by board directly but are connected to
external connector:
http://www.hardkernel.com/main/products/prdt_info.php?g_code=G143452239825&tab_idx=2
This is the 12pin GPIO/I2C/I2S connector in bottom-right corner of board
view.
This is why I left this and is2_0 enabled on Odroid XU4 - I assumed
someone may connect something to it. However I have doubts if it is
usable in such state: without respective addresses and interrupts. In
the same time OF_OVERLAY should customize it properly.
What do you think?
Thanks for review,
Best regards,
Krzysztof
