Merge branch 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into omap/cleanup
* 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap:
ARM: OMAP2+: Fix L4_EMU_34XX_BASE error after iomap changes
ARM: OMAP2+: Limit omap_read/write usage to legacy USB drivers
ARM: OMAP: Remove plat/io.h by splitting it into mach/io.h and mach/hardware.h
ARM: OMAP2+: Move most of plat/io.h into local iomap.h
ARM: OMAP1: Move most of plat/io.h into local iomap.h
ARM: OMAP1: Move 16xx GPIO system clock to platform init code
ARM: OMAP: Move omap_init_consistent_dma_size() to local common.h
ARM: OMAP2+: Move SDRC related functions from io.h into local common.h
ARM: OMAP2+: Drop DISPC L3 firewall code
ARM: OMAP2xxx: PM: remove obsolete timer disable code in the suspend path
ARM: OMAP: McSPI: Remove unused flag from struct omap2_mcspi_device_config
