Merge tag 'mvebu' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC updates for Marvell mvebu/kirkwood from Olof Johansson: "This is a branch with updates for Marvell's mvebu/kirkwood platforms. They came in late-ish, and were heavily interdependent such that it didn't make sense to split them up across the cross-platform topic branches. So here they are (for the second release in a row) in a branch on their own." * tag 'mvebu' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (88 commits) arm: l2x0: add aurora related properties to OF binding arm: mvebu: add Aurora L2 Cache Controller to the DT arm: mvebu: add L2 cache support dma: mv_xor: fix error handling path dma: mv_xor: fix error checking of irq_of_parse_and_map() dma: mv_xor: use request_irq() instead of devm_request_irq() dma: mv_xor: clear the window override control registers arm: mvebu: fix address decoding armada_cfg_base() function ARM: mvebu: update defconfig with I2C and RTC support ARM: mvebu: Add SATA support for OpenBlocks AX3-4 ARM: mvebu: Add support for the RTC in OpenBlocks AX3-4 ARM: mvebu: Add support for I2C on OpenBlocks AX3-4 ARM: mvebu: Add support for I2C controllers in Armada 370/XP arm: mvebu: Add hardware I/O Coherency support arm: plat-orion: Add coherency attribute when setup mbus target arm: dma mapping: Export a dma ops function arm_dma_set_mask arm: mvebu: Add SMP support for Armada XP arm: mm: Add support for PJ4B cpu and init routines arm: mvebu: Add IPI support via doorbells arm: mvebu: Add initial support for power managmement service unit ...
