[PATCH v3] asm-generic/gpio.h: merge basic gpiolib wrappers
Mike Frysinger
vapier at gentoo.org
Thu Nov 3 14:45:39 EST 2011
Rather than requiring architectures that use gpiolib but don't have
any need to define anything custom to copy an asm/gpio.h, merge this
code into the asm-generic/gpio.h. We add ifdef checks so that arches
can still override things while using the asm-generic/gpio.h, but on
a more fine grained per-func approach.
I've compile tested these guys (with & without GPIOLIB), but don't
have the hardware to boot:
- alpha defconfig
- arm: all defconfigs
- blackfin defconfig
- ia64 defconfig
- m68k: multi & m5208evb defconfig
- mips: ar7 & ath79 & bcm47xx & bcm63xx & ip22 defconfig
- powerpc: mpc85xx & ppc64 defconfig
- sh: kfr2r09 defconfig
- sparc defconfig
- x86_64 defconfig
I don't have any toolchains for avr32, microblaze, openrisc, unicore32,
or xtensa. So they lose :x.

v3
- built on top of Linus' recent gpio fixes
- fixes builds for one or two arm platforms
- all the arm defconfigs have been checked on the disassembly level
