Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC cleanups on various subarchitectures from Olof Johansson: "Cleanup patches for various ARM platforms and some of their associated drivers. There's also a branch in here that enables Freescale i.MX to be part of the multiplatform support -- the first "big" SoC that is moved over (more multiplatform work comes in a separate branch later during the merge window)." Conflicts fixed as per Olof, including a silent semantic one in arch/arm/mach-omap2/board-generic.c (omap_prcm_restart() was renamed to omap3xxx_restart(), and a new user of the old name was added). * tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (189 commits) ARM: omap: fix typo on timer cleanup ARM: EXYNOS: Remove unused regs-mem.h file ARM: EXYNOS: Remove unused non-dt support for dwmci controller ARM: Kirkwood: Use hw_pci.ops instead of hw_pci.scan ARM: OMAP3: cm-t3517: use GPTIMER for system clock ARM: OMAP2+: timer: remove CONFIG_OMAP_32K_TIMER ARM: SAMSUNG: use devm_ functions for ADC driver ARM: EXYNOS: no duplicate mask/unmask in eint0_15 ARM: S3C24XX: SPI clock channel setup is fixed for S3C2443 ARM: EXYNOS: Remove i2c0 resource information and setting of device names ARM: Kirkwood: checkpatch cleanups ARM: Kirkwood: Fix sparse warnings.

+/*
+ * This is rather complicated for humans and ugly to verify, but for a machine
+ * it's OK. Still more as it is usually only applied to constants. The upsides
+ * on using this approach are:
+ *
+ * - same mapping on all i.MX machines
+ * - works for assembler, too
+ * - no need to nurture #defines for virtual addresses
+ *
+ * The downside it, it's hard to verify (but I have a script for that).
+ *
+ * Obviously this needs to be injective for each SoC. In general it maps the
+ * whole address space to [0xf4000000, 0xf5ffffff]. So [0xf6000000,0xfeffffff]
+ * is free for per-machine use (e.g. KZM_ARM11_01 uses 64MiB there).
+ *
+ * It applies the following mappings for the different SoCs:
