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.
Then why not add this header (or move it to the header file) when your
board setup code is merged? No need to have it there now, right?
Cause everyone who want's to use this driver for his board needs the
header. The board I use is a prototype, nearly the same as some Atmel
Demo board, but with the sc16is752 attached to the SPI port. Therefore I
don't see any benefit in publishing my board setup code.
Care to resend this driver changed that way?
As I said the header definitely belongs to the driver, not to the board.
