Merge tag 'omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/headers
From Tony Lindgren <tony@atomide.com>: These changes deal with the issues of relative includes introduced by the earlier clean-up and clean up few more things for enabling multiplatform support. The multiplatform kernel has been booted on omaps on top of this branch with the work-in-progress patches applied manually. We cannot yet enable the multiplatform support though. We still need the common clock framework patches, some solution for dma-omap.h, and serial-omap.h moved before we can enable it. * tag 'omap-for-v3.8/cleanup-headers-prepare-multiplatform-v3-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ARM: OMAP: Remove omap_init_consistent_dma_size() ARM: OMAP: Remove NEED_MACH_GPIO_H ARM: OMAP: Remove unnecessary mach and plat includes ARM: OMAP2+: Fix relative includes for serial.h ARM: OMAP: Fix relative includes for fpga.h ARM: OMAP1: Remove relative includes ARM: OMAP: Remove cpu_is_omap usage from plat-omap/dma.c ARM: OMAP: Fix relative includes for debug-devices.h ARM: OMAP: Remove plat-omap/common.h ARM: OMAP: Move omap-pm-noop.c local to mach-omap2 ARM: OMAP: Fix relative includes for shared i2c.h file ARM: OMAP: Make plat-omap/i2c.c port checks local ARM: OMAP: Move omap2+ specific parts of sram.c to mach-omap2 ARM: OMAP: Move omap1 specific code to local sram.c ARM: OMAP: Introduce common omap_map_sram() and omap_sram_reset() ARM: OMAP: Split sram.h to local headers and minimal shared header ARM: OMAP1: usb: fix sparse warnings Conflicts: arch/arm/mach-omap2/cm33xx.c Signed-off-by: Arnd Bergmann <arnd@arndb.de>
