Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM soc general cleanups from Olof Johansson: "This is a large branch that contains a handful of different cleanups: - Fixing up the I/O space remapping on PCI on ARM. This is a series from Rob Herring that restructures how all pci devices allocate I/O space, and it's part of the work to allow multiplatform kernels. - A number of cleanup series for OMAP, moving and removing some headers, sparse irq rework and in general preparation for multiplatform. - Final removal of all non-DT boards for Tegra, it is now device-tree-only! - Removal of a stale platform, nxp4008. It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel. We have not been able to find anyone interested in keeping it around in the kernel. - Removal of the legacy dmaengine driver on tegra + A handful of other things that I haven't described above." Fix up some conflicts with the staging tree (and because nxp4008 was removed) * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (184 commits) ARM: OMAP2+: serial: Change MAX_HSUART_PORTS to 6 ARM: OMAP4: twl-common: Support for additional devices on i2c1 bus ARM: mmp: using for_each_set_bit to simplify the code ARM: tegra: harmony: fix ldo7 regulator-name ARM: OMAP2+: Make omap4-keypad.h local ARM: OMAP2+: Make l4_3xxx.h local ARM: OMAP2+: Make l4_2xxx.h local ARM: OMAP2+: Make l3_3xxx.h local ARM: OMAP2+: Make l3_2xxx.h local ARM: OMAP1: Move irda.h from plat to mach ARM: OMAP2+: Make hdq1w.h local ARM: OMAP2+: Make gpmc-smsc911x.h local ARM: OMAP2+: Make gpmc-smc91x.h local ARM: OMAP1: Move flash.h from plat to mach ARM: OMAP2+: Make debug-devices.h local ARM: OMAP1: Move board-voiceblue.h from plat to mach ARM: OMAP1: Move board-sx1.h from plat to mach ARM: OMAP2+: Make omap-wakeupgen.h local ARM: OMAP2+: Make omap-secure.h local ARM: OMAP2+: Make ctrl_module_wkup_44xx.h local ...
