PATCH 1/1 ARM: dts: omap3430-sdp: add dip switch information for MMC operation
MMC 8 bit mode operation depends on dip switch setting which is not obvious - The current board file has this description. However, with removal of the board file in the future, this information will be lost and has to be rediscovered.
