Merge tag 'omap-for-v3.9/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 to add device tree bindings. * tag 'omap-for-v3.9/gpmc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP2+: gpmc: Add device tree documentation for elm handle ARM: OMAP2+: gpmc: add DT bindings for OneNAND ARM: OMAP2+: gpmc-onenand: drop __init annotation mtd: omap-onenand: pass device_node in platform data ARM: OMAP2+: Prevent potential crash if GPMC probe fails ARM: OMAP2+: gpmc: Remove unneeded of_node_put() ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND ARM: OMAP: gpmc: enable hwecc for AM33xx SoCs ARM: OMAP: gpmc-nand: drop __init annotation mtd: omap-nand: pass device_node in platform data ARM: OMAP: gpmc: don't create devices from initcall on DT Signed-off-by: Olof Johansson <olof@lixom.net>
