Merge tag 'drivers_for_v3.9' of git://git.infradead.org/users/jcooper/linux into next/soc
From Jason Cooper: mvebu drivers for v3.9 - use rtc-mv in mvebu armv7 SoCs - add pci-e hotplug for kirkwood Depends on: - tags/mvebu_fixes_for_v3.8-rc6 * tag 'drivers_for_v3.9' of git://git.infradead.org/users/jcooper/linux: cpuidle: kirkwood: Move out of mach directory rtc: Add support of rtc-mv for MVEBU SoCs ARM: Kirkwood: Support basic hotplug for PCI-E arm: mvebu: i2c come back in defconfig arm: plat-orion: fix printing of "MPP config unavailable on this hardware" Dove: activate GPIO interrupts in DT
