[PATCH 3/5] ARM: dts: at91: Update board dts to use the new EBI/NAND bindings
Boris Brezillon
boris.brezillon at free-electrons.com
Tue May 30 01:32:48 PDT 2017
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).
