this one adds an #include <asm/arch/regs-gpio.h>. Tested by Roman Moravcik on s3c2440. Based on the discussion last december (http://lkml.org/lkml/2006/12/20/243), this patch - fixes comment and includes in gpio.h - adds the gpio_to_irq definition for S3C2400 - includes asm/arch/regs-gpio.h for pin direction definitions Signed-off-by: Philipp Zabel <philipp.zabel@gmail.com> Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
