tks for the patch but now we have close the non dt board for this soc

and for 3.5 nearly all the devices of this soc will converted to DT

so you need to switch to DT too

As today I've not finished the pinctrl support you need to do all the pin mux
in the bootlader. For 3.5 it will not be the case anymore

Best Rebards,
J.

Ok, i will switch to DT too.
Do you plan to add support to any 9260 board to the board-dt.c for 3.5?
I think that, as far as there is a working 9260 board using DT, i can
work on the GE863-PRO3 support using DT.

Ok i try with the 9g20 support.
