Why is this needed in a .h file? What other .c file uses this define
and structure?
thanks,

The board setup code can pass information about the uart and gpio
enumeration.
What "board setup code"? I don't see that here in the patch anywhere.
SPI devices are generally set up for a specific hardware board. I.e. for
some ARM boards there is setup code in
linux/arch/arm/mach-at91/board-<xyz>.c
I use the sc16is7x2 for a board that is not yet in vanilla, so the board
setup code is not included in the patch.
