Pull ARM driver updates from Olof Johansson: "Updates of SoC-near drivers and other driver updates that makes more sense to take through our tree. In this case it's involved: - Some Davinci driver updates that has required corresponding platform code changes (gpio mostly) - CCI bindings and a few driver updates - Marvell mvebu patches for PCI MSI support (could have gone through the PCI tree for this release, but they were acked by Bjorn for 3.12 so we kept them through arm-soc). - Marvell dove switch-over to DT-based PCIe configuration - Misc updates for Samsung platform dmaengine drivers" * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (32 commits) ARM: S3C24XX: add dma pdata for s3c2410, s3c2440 and s3c2442 dmaengine: s3c24xx-dma: add support for the s3c2410 type of controller ARM: S3C24XX: Fix possible dma selection warning PCI: mvebu: make local functions static PCI: mvebu: add I/O access wrappers PCI: mvebu: Dynamically detect if the PEX link is up to enable hot plug ARM: mvebu: fix gated clock documentation ARM: dove: remove legacy pcie and clock init ARM: dove: switch to DT probed mbus address windows ARM: SAMSUNG: set s3c24xx_dma_filter for s3c64xx-spi0 device ARM: S3C24XX: add platform-devices for new dma driver for s3c2412 and s3c2443 dmaengine: add driver for Samsung s3c24xx SoCs ARM: S3C24XX: number the dma clocks PCI: mvebu: add support for Marvell Dove SoCs PCI: mvebu: add support for reset on GPIO PCI: mvebu: remove subsys_initcall PCI: mvebu: increment nports only for registered ports PCI: mvebu: move clock enable before register access PCI: mvebu: add support for MSI irqchip: armada-370-xp: implement MSI support ...

Pull ARM SoC platform changes from Olof Johansson: "New and updated SoC support. Among the things new for this release are: - More support for the AM33xx platforms from TI - Tegra 124 support, and some updates to older tegra families as well - imx cleanups and updates across the board - A rename of Broadcom's Mobile platforms which were introduced as ARCH_BCM, and turned out to be too broad a name. New name is ARCH_BCM_MOBILE. - A whole bunch of updates and fixes for integrator, making the platform code more modern and switches over to DT-only booting. - Support for two new Renesas shmobile chipsets. Next up for them is more work on consolidation instead of introduction of new non-multiplatform SoCs, we're all looking forward to that! - Misc cleanups for older Samsung platforms, some Allwinner updates, etc" * tag 'soc-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (159 commits) ARM: bcm281xx: Add ARCH_BCM_MOBILE to bcm config ARM: bcm_defconfig: Run "make savedefconfig" ARM: bcm281xx: Add ARCH Timers to config rename ARCH_BCM to ARCH_BCM_MOBILE (mach-bcm) ARM: vexpress: Enable platform-specific options in defconfig ARM: vexpress: Make defconfig work again ARM: sunxi: remove .init_time hooks ARM: imx: enable suspend for imx6sl ARM: imx: ensure dsm_request signal is not asserted when setting LPM ARM: imx6q: call WB and RBC configuration from imx6q_pm_enter() ARM: imx6q: move low-power code out of clock driver ARM: imx: drop extern with function prototypes in common.h ARM: imx: reset core along with enable/disable operation ARM: imx: do not return from imx_cpu_die() call ARM: imx_v6_v7_defconfig: Select CONFIG_PROVE_LOCKING ARM: imx_v6_v7_defconfig: Enable LEDS_GPIO related options ARM: mxs_defconfig: Turn off CONFIG_DEBUG_GPIO ARM: imx: replace imx6q_restart() with mxc_restart() ARM: mach-imx: mm-imx5: Retrieve iomuxc base address from dt ARM: mach-imx: mm-imx5: Retrieve tzic base address from dt ...

2013-10-31ARM: 7857/1: dma: imx-sdma: setup dma maskPhilippe Retornaz1-0/+4
The dma mask is not configured in the current code. This was triggered by soc-dmaengine-pcm which allocate the dma buffers with the imx-sdma as device. This commit fix audio on imx31.

2013-10-31DMA-API: dma: edma.c: no need to explicitly initialize DMA masksRussell King1-4/+6
register_platform_device_full() can setup the DMA mask provided the appropriate member is set in struct platform_device_info. So lets make that be the case. This avoids a direct reference to the DMA masks by this driver. While here, add the dma_set_mask_and_coherent() call which the DMA API requires DMA-using drivers to call.

2013-10-31DMA-API: dma: dw_dmac.c: convert to use dma_coerce_mask_and_coherent()Russell King1-5/+3
This code sequence: if (!pdev->dev.dma_mask) { pdev->dev.dma_mask = &pdev->dev.coherent_dma_mask; pdev->dev.coherent_dma_mask = DMA_BIT_MASK(32); } bypasses the architectures check on the DMA mask. It can be replaced with dma_coerce_mask_and_coherent(), avoiding the direct initialization of this mask. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2013-10-21dma: edma: Increase maximum SG limit to 20Joel Fernandes1-2/+8
davinci-pcm uses 16 as the no.of periods. With this, in EDMA we have to allocate atleast 17 slots: 1 slot for channel, and 16 slots the periods. Due to this, the MAX_NR_SG limitation causes problems, set it to 20 to make cyclic DMA work when davinci-pcm is converted to use DMA Engine. Also add a comment clarifying this.

2013-10-21dma: edma: Split out PaRAM set calculations into its own functionJoel Fernandes1-72/+126
PaRAM set calculation is abstracted into its own function to enable better reuse for other DMA cases such as cyclic. We adapt the Slave SG case to use the new function. This provides a much cleaner abstraction to the internals of the PaRAM set. However, any PaRAM attributes that are not common to all DMA types must be set separately such as setting of interrupts. This function takes care of the most-common attributes. Also added comments clarifying A-sync case calculations.
