[PATCH v6 1/5] ARM: OMAP: gpmc: don't create devices from initcall on DT

From: zonque@gmail.com (Daniel Mack)
Date: 2012-11-29 16:01:28
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

On DT driven boards, the gpmc node will match the driver. Hence, there's
no need to do that unconditionally from the initcall.
