Merge tag 'fixes-3.12-2' of git://git.infradead.org/linux-mvebu into fixes
From Jason Cooper: mvebu fixes for v3.12 (round 2) - mvebu - fix ReadyNAS 102 power button (needs to be active high) - fix ReadyNAS 102 automated rebooting (prevent hang) by add gpio-poweroff node - fix booting ReadyNAS 102 by adding MBus ranges and PCIe DT nodes - mvebu-mbus: prevent PCIe driver from continuing with corrupted resource * tag 'fixes-3.12-2' of git://git.infradead.org/linux-mvebu: bus: mvebu-mbus: Fix optional pcie-mem/io-aperture properties ARM: mvebu: add missing DT Mbus ranges and relocate PCIe DT nodes for RN102 ARM: mvebu: Add DT entry for ReadyNAS 102 to use gpio-poweroff driver ARM: mvebu: fix ReadyNAS 102 Power button GPIO to make it active high Signed-off-by: Olof Johansson <olof@lixom.net>
