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. However, it is not trivial to just create a branch to remove it. Over the course of the v3.9 cycle more code referencing GENERIC_GPIO has been added to linux-next that conflicts with this branch. The following must be done to resolve the conflicts when merging this branch into mainline: * "git grep CONFIG_GENERIC_GPIO" should return 0 hits. Matches should be replaced with CONFIG_GPIOLIB * "git grep '\bGENERIC_GPIO\b'" should return 1 hit in the Chinese documentation. * Selectors of GENERIC_GPIO should be turned into selectors of GPIOLIB * definitions of the option in architecture Kconfig code should be deleted. Stephen has 3 merge fixup patches[1] that do the above. They are currently applicable on mainline as of May 2nd.
