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
