Merge tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC board updates from Olof Johansson: "Board updates for 3.12. Again, a bit of domain overlap with SoC and DT branches, but most of this is around legacy code and board support. We've found that platform maintainers have a hard time separating all of these out and might move towards fewer branches for next release. - Removal of a number of Marvell Kirkwood board files, since contents is now common and mostly configured via DT. - Device-tree updates for Marvell Dove, including irqchip and clocksource setup. - Defconfig updates. Gotta go somewhere. One new one for Renesas Lager. - New backlight drivers for backlights used on Renesas shmobile platforms. - Removal of Renesas leds driver. - Shuffling of some of the new Broadcom platforms to give room for others in the same mach directory. More in 3.13" * tag 'boards-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (67 commits) mmc: sdhci-bcm-kona: Staticize sdhci_bcm_kona_card_event mmc: sdhci-bcm-kona: Remove unneeded version.h inclusion ARM: bcm: Make secure API call optional ARM: DT: binding fixup to align with vendor-prefixes.txt (drivers) ARM: mmc: fix NONREMOVABLE test in sdhci-bcm-kona ARM: bcm: Rename board_bcm mmc: sdhci-bcm-kona: make linker-section warning go away ARM: tegra: defconfig updates ARM: dove: add initial DT file for Globalscale D2Plug ARM: dove: add GPIO IR receiver node to SolidRun CuBox ARM: dove: add common pinmux functions to DT ARM: dove: add cpu device tree node ARM: dove: update dove_defconfig with SI5351, PCI, and xHCI arch/arm/mach-kirkwood: Avoid using ARRAY_AND_SIZE(e) as a function argument ARM: kirkwood: fix DT building and update defconfig ARM: kirkwood: Remove all remaining trace of DNS-320/325 platform code ARM: configs: disable DEBUG_LL in bcm_defconfig ARM: bcm281xx: Board specific reboot code ARM bcm281xx: Turn on socket & network support.
