Merge branch 'fixes' into next/cleanup
Merging in fixes since there's a conflict in the omap4 clock tables caused by it. * fixes: (245 commits) ARM: highbank: fix cache flush ordering for cpu hotplug ARM: OMAP4: hwmod data: make 'ocp2scp_usb_phy_phy_48m" as the main clock arm: mvebu: Fix the irq map function in SMP mode Fix GE0/GE1 init on ix2-200 as GE0 has no PHY ARM: S3C24XX: Fix interrupt pending register offset of the EINT controller ARM: S3C24XX: Correct NR_IRQS definition for s3c2440 ARM i.MX6: Fix ldb_di clock selection ARM: imx: provide twd clock lookup from device tree ARM: imx35 Bugfix admux clock ARM: clk-imx35: Bugfix iomux clock + Linux 3.9-rc6 Signed-off-by: Olof Johansson <olof@lixom.net> Conflicts: arch/arm/mach-omap2/cclock44xx_data.c
