[PATCH V2 13/17] ARM: OMAP2+: Convert NAND to retrieve GPMC settings from DT

From: Jon Hunter <hidden>
Date: 2013-03-08 16:58:34
Also in: linux-devicetree, linux-omap
Subsystem: arm port, omap general purpose memory controller support, omap power management support, omap2+ support, the rest · Maintainers: Russell King, Roger Quadros, Tony Lindgren, Kevin Hilman, Aaro Koskinen, Andreas Kemnade, Linus Torvalds

When booting with device-tree, retrieve GPMC settings for NAND from
the device-tree blob. This will allow us to remove all static settings
stored in the gpmc-nand.c in the future once the migration to
device-tree is complete.
