Commit Message

Boris Brezillon May 30, 2017, 8:32 a.m. UTC 
The NAND controller bindings have been changed to match the hardware
topology (where the NAND controller is under the EBI bus).

This new representation is needed in order to define non-NAND devices
under the EBI bus (otherwise we face pinmux conflicts).
