[PATCH 1/8] ARM: OMAP2+: Move DISPC L3 firewall to happen in omap_display_init()
From: Tony Lindgren <tony@atomide.com>
Date: 2012-02-21 23:40:35
Also in:
linux-arm-kernel, linux-omap
Subsystem:
arm port, framebuffer layer, omap2+ support, the rest · Maintainers:
Russell King, Helge Deller, Aaro Koskinen, Andreas Kemnade, Kevin Hilman, Roger Quadros, Tony Lindgren, Linus Torvalds
Otherwise we cannot move most of plat/io.h to be a local iomap.h for mach-omap2.
