Also in:
linux-devicetree, lkml
Subsystem:
arm port, arm/microchip (at91) soc support, memory controller drivers, open firmware and flattened device tree bindings, the rest · Maintainers:
Russell King, Nicolas Ferre, Alexandre Belloni, Claudiu Beznea, Krzysztof Kozlowski, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds
at91sam9* and sama5d* SoCs have an EBI (External Bus Interface). Select the ATMEL_EBI driver when support for these SoCs is selected.
