Merge tag 'gpmc-omap-for-v4.8' of https://github.com/rogerq/linux into next/drivers
OMAP-GPMC: driver updates for v4.8 * Make GPMC driver non modular as it is going to be built-in only till arch/arm/mach-omap2 users are removed. * Fix build if CONFIG_OF is not defined. * tag 'gpmc-omap-for-v4.8' of https://github.com/rogerq/linux: memory: omap-gpmc: Move gpio functions out of #ifdef CONFIG_OF memory: omap-gpmc: make it explicitly non-modular Signed-off-by: Olof Johansson <olof@lixom.net>
