Merge tag 'omap-for-v3.11/gpmc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
From Tony Lindgren:
Omap GPMC (General Purpose Memory Controller) changes.
* tag 'omap-for-v3.11/gpmc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: gpmc: Converts GPMC driver to pm_runtime capable
ARM: OMAP2+: gpmc: get number of useable GPMC chip-selects via DT
ARM: dts: OMAP2+: Simplify NAND support
ARM: OMAP2+: Allow NAND transfer mode to be specified in DT
ARM: OMAP2+: nand: reorganize gpmc timing values
