Merge tag 'ux500-dma40-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into next/drivers
From Linus Walleij: This is a set of patches from Lee Jones to start converting the ux500 to fetch DMA channels from the device tree: - Full DT support and channel mapping in the DMA40 driver - Dropping of platform data for migrated devices on the DT boot path. * tag 'ux500-dma40-for-arm-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson: (36 commits) ARM: ux500: Register Cryp and Hash platform drivers on Snowball crypto: ux500/[cryp|hash] - Show successful start-up in the bootlog ARM: ux500: Stop passing Cryp DMA channel config information though pdata crypto: ux500/cryp - Set DMA configuration though dma_slave_config() crypto: ux500/cryp - Prepare clock before enabling it ARM: ux500: Stop passing Hash DMA channel config information though pdata crypto: ux500/hash - Set DMA configuration though dma_slave_config() crypto: ux500/hash - Prepare clock before enabling it ARM: ux500: Remove unnecessary attributes from DMA channel request pdata dmaengine: ste_dma40: Correct copy/paste error ARM: ux500: Remove DMA address look-up table dmaengine: ste_dma40: Remove redundant address fetching function dmaengine: ste_dma40: Only use addresses passed as configuration information ARM: ux500: Stop passing UART's platform data for Device Tree boots dmaengine: ste_dma40: Don't configure runtime configurable setup during allocate dmaengine: ste_dma40: Remove unnecessary call to d40_phy_cfg() dmaengine: ste_dma40: Separate Logical Global Interrupt Mask (GIM) unmasking ARM: ux500: Pass remnant platform data though to DMA40 driver dmaengine: ste_dma40: Supply full Device Tree parsing support dmaengine: ste_dma40: Allow driver to be probe()able when DT is enabled ...
