[PATCH 6/9] ARM: at91/dt: add spi0 support to at91rm9200ek board

Boris BREZILLON
2013-08-28T11:08:19Z

Add spi0 cs3 switch pinctrl pin definitions: this pin is used to select
between mmc0 slot0 and spi dataflash connected to cs3.

Enable spi0 controller and define the mtd_dataflash connected to cs0.
