Merge tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC fixes from Olof Johansson: "We didn't have a batch last week, so this one is slightly larger. None of them are scary though, a handful of fixes for small DT pieces, replacing properties with newer conventions. Highlights: - N900 fix for setting system revision - onenand init fix to avoid filesystem corruption - Clock fix for audio on Beaglebone-x15 - Fixes on shmobile to deal with CONFIG_DEBUG_RODATA (default y in 4.6) + misc smaller stuff" * tag 'armsoc-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: MAINTAINERS: Extend info, add wiki and ml for meson arch MAINTAINERS: alpine: add a new maintainer and update the entry ARM: at91/dt: fix typo in sama5d2 pinmux descriptions ARM: OMAP2+: Fix onenand initialization to avoid filesystem corruption Revert "regulator: tps65217: remove tps65217.dtsi file" ARM: shmobile: Remove shmobile_boot_arg ARM: shmobile: Move shmobile_smp_{mpidr, fn, arg}[] from .text to .bss ARM: shmobile: r8a7779: Remove remainings of removed SCU boot setup code ARM: shmobile: Move shmobile_scu_base from .text to .bss ARM: OMAP2+: Fix omap_device for module reload on PM runtime forbid ARM: OMAP2+: Improve omap_device error for driver writers ARM: DTS: am57xx-beagle-x15: Select SYS_CLK2 for audio clocks ARM: dts: am335x/am57xx: replace gpio-key,wakeup with wakeup-source property ARM: OMAP2+: Set system_rev from ATAGS for n900 ARM: dts: orion5x: fix the missing mtd flash on linkstation lswtgl ARM: dts: kirkwood: use unique machine name for ds112 ARM: dts: imx6: remove bogus interrupt-parent from CAAM node
