From: Russell King Date: Mon, 21 Nov 2011 21:56:56 +0000 (+0000) Subject: Merge branch 'irqchip-consolidation' of git://git.kernel.org/pub/scm/linux/kernel... X-Git-Tag: firefly_0821_release~3680^2~2832^2~2^2~36 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=2d13ccaa8797d7e599f3792aed4b1e44b47f94a5;p=firefly-linux-kernel-4.4.55.git Merge branch 'irqchip-consolidation' of git://git./linux/kernel/git/maz/arm-platforms into devel-stable Conflicts: arch/arm/mach-omap2/board-4430sdp.c arch/arm/mach-omap2/board-omap4panda.c arch/arm/mach-omap2/include/mach/omap4-common.h arch/arm/plat-omap/include/plat/irqs.h The changes to omap4-common.h were moved to arch/arm/mach-omap2/common.h and the other trivial conflicts resolved. The now empty ifdef in irqs.h was also eliminated. --- 2d13ccaa8797d7e599f3792aed4b1e44b47f94a5 diff --cc arch/arm/mach-omap2/board-4430sdp.c index cff2e3249fee,21e31d499745..ef2bbc09428a --- a/arch/arm/mach-omap2/board-4430sdp.c +++ b/arch/arm/mach-omap2/board-4430sdp.c @@@ -27,6 -27,8 +27,7 @@@ #include #include -#include + #include #include #include #include diff --cc arch/arm/mach-omap2/board-omap4panda.c index 7722d4d97fb9,aa9465e79bfc..b6f114436dbc --- a/arch/arm/mach-omap2/board-omap4panda.c +++ b/arch/arm/mach-omap2/board-omap4panda.c @@@ -30,6 -30,8 +30,7 @@@ #include #include -#include + #include #include #include #include diff --cc arch/arm/mach-omap2/common.h index 950b39d76e94,000000000000..18c4d5d20faf mode 100644,000000..100644 --- a/arch/arm/mach-omap2/common.h +++ b/arch/arm/mach-omap2/common.h @@@ -1,185 -1,0 +1,183 @@@ +/* + * Header for code common to all OMAP2+ machines. + * + * This program is free software; you can redistribute it and/or modify it + * under the terms of the GNU General Public License as published by the + * Free Software Foundation; either version 2 of the License, or (at your + * option) any later version. + * + * THIS SOFTWARE IS PROVIDED ``AS IS'' AND ANY EXPRESS OR IMPLIED + * WARRANTIES, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF + * MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE ARE DISCLAIMED.
