* gpiolib/arches: Centralise bolierplate asm/gpio.hMark Brown2012-05-111-53/+4
| | | | | | | | | | | | | | | | | | | | | Rather than requiring architectures that use gpiolib but don't have any need to define anything custom to copy an asm/gpio.h provide a Kconfig symbol which architectures must select in order to include gpio.h and for other architectures just provide the trivial implementation directly. This makes it much easier to do gpiolib updates and is also a step towards making gpiolib APIs available on every architecture. For architectures with existing boilerplate code leave a stub header in place which warns on direct inclusion of asm/gpio.h and includes linux/gpio.h to catch code that's doing this. Direct inclusion of asm/gpio.h has long been deprecated.

* powerpc/gpio: support gpio_to_irq()Peter Korsgaard2009-12-101-4/+1
| | | | | | | | gpiolib returns -ENXIO if struct gpio_chip::to_irq isn't set, so it's safe to always call. Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
* powerpc: Move include files to arch/powerpc/include/asmStephen Rothwell2008-08-041-0/+56
from include/asm-powerpc. This is the result of a mkdir arch/powerpc/include/asm git mv include/asm-powerpc/* arch/powerpc/include/asm Followed by a few documentation/comment fixups and a couple of places where <asm-powepc/...> was being used explicitly. Of the latter only one was outside the arch code and it is a driver only built for powerpc. Signed-off-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
