Merge tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux
Pull removal of GENERIC_GPIO from Grant Likely: "GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage. This branch does the work to completely eliminate GENERIC_GPIO." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux: gpio: update gpio Chinese documentation Remove GENERIC_GPIO config option Convert selectors of GENERIC_GPIO to GPIOLIB blackfin: force use of gpiolib m68k: coldfire: use gpiolib mips: pnx833x: remove requirement for GENERIC_GPIO openrisc: default GENERIC_GPIO to false avr32: default GENERIC_GPIO to false xtensa: remove explicit selection of GENERIC_GPIO sh: replace CONFIG_GENERIC_GPIO by CONFIG_GPIOLIB powerpc: remove redundant GENERIC_GPIO selection unicore32: default GENERIC_GPIO to false unicore32: remove unneeded select GENERIC_GPIO arm: plat-orion: use GPIO driver on CONFIG_GPIOLIB arm: remove redundant GENERIC_GPIO selection mips: alchemy: require gpiolib mips: txx9: change GENERIC_GPIO to GPIOLIB mips: loongson: use GPIO driver on CONFIG_GPIOLIB mips: remove redundant GENERIC_GPIO select
