Merge branch 'depends/omap/gpio/runtime-pm-cleanup' into next/cleanup
Conflicts: arch/arm/mach-omap1/gpio16xx.c drivers/gpio/gpio-omap.c Merge in the runtime-pm-cleanup branch from the gpio tree into next/cleanup, this resolves a nonobvious merge conflict between the two branches. Both branches move parts of the gpio-omap driver into platform code, this takes the superset of both changes. Signed-off-by: Arnd Bergmann <arnd@arndb.de>
