Hi, This patchset adds support for the DMA controller found in the Allwinner A31 and A23 SoCs. This has been tested using the newly introduced SPI driver on an A31 EVK. Support for DMA-driven SPI transfers will be the subject of another patch serie. Since this serie has been sent for the first time about 2 monthes ago, and I never got any comments from the DMA maintainer, yet gathering some Acked-by, I expect this to be merged quite quickly. Thanks, Maxime Changes from v5: - Rebased on top of 3.15-rc1 Changes from v4: - Removed the packed attribute on the LLI - Switched to using a NULL device pointer in clk_get on PLL6 and AHB1 mux to make explicit that we are getting global clocks - Switched from spin_lock_irqsave to spin_lock in the interrupt handler - Various nitpicks from Andy Shevchenko: + Switched to using %p printk formats for pointers + Inverted some tests to lose a level of indentation + Dropped ifdef DEBUG protecting calls to dev_dbg Changes from v3: - A few other comments made by Andy Shevchenko were fixed: + Used references in %pa* printk formats + Used is_slave_direction in prep_slave_sg to make sure we were actually called for something, and to avoid making assumptions that we were actually called with the expected directions + A few others minor fixes: s/pr_err/dev_err/, etc. Changes from v2: - Removed the clk_put calls in the clock protection functions - Splitted out the sunxi machines into several files - Moved the clock protection code into these new machine files - Moved the PLL6 reparenting to the DMA driver - Addressed various comments from Andy Shevchenko: switched to using devm_kcalloc, used correct printk formats for physical and DMA addresses, etc. Changes from v1: - Removed the clk_put call in the clocks protecting patches - Minor fixes here and there as suggested by Andy Shevchenko: switch to dmam_pool_create, switch to dev_dbg instead of pr_debug, etc. Maxime Ripard (8): clk: sunxi: Remove calls to clk_put ARM: sunxi: Split out the various machines into separate files ARM: sunxi: Move the clock protection to machine hooks ARM: sun6i: Protect CPU clock ARM: sun6i: Protect SDRAM gating bit ARM: sun6i: Sort the NMI node by physical address DMA: sun6i: Add driver for the Allwinner A31 DMA controller ARM: sun6i: dt: Add A31 DMA controller to DTSI .../devicetree/bindings/dma/sun6i-dma.txt | 45 + arch/arm/boot/dts/sun6i-a31.dtsi | 41 +- arch/arm/mach-sunxi/Makefile | 6 +- arch/arm/mach-sunxi/restart.c | 104 +++ arch/arm/mach-sunxi/restart.h | 20 + arch/arm/mach-sunxi/sun4i.c | 45 + arch/arm/mach-sunxi/sun5i.c | 51 ++ arch/arm/mach-sunxi/sun6i.c | 63 ++ arch/arm/mach-sunxi/sun7i.c | 50 ++ arch/arm/mach-sunxi/sunxi.c | 164 ---- drivers/clk/sunxi/clk-sunxi.c | 28 - drivers/dma/Kconfig | 8 + drivers/dma/Makefile | 1 + drivers/dma/sun6i-dma.c | 987 +++++++++++++++++++++ 14 files changed, 1414 insertions(+), 199 deletions(-) create mode 100644 Documentation/devicetree/bindings/dma/sun6i-dma.txt create mode 100644 arch/arm/mach-sunxi/restart.c create mode 100644 arch/arm/mach-sunxi/restart.h create mode 100644 arch/arm/mach-sunxi/sun4i.c create mode 100644 arch/arm/mach-sunxi/sun5i.c create mode 100644 arch/arm/mach-sunxi/sun6i.c create mode 100644 arch/arm/mach-sunxi/sun7i.c delete mode 100644 arch/arm/mach-sunxi/sunxi.c create mode 100644 drivers/dma/sun6i-dma.c -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to email@example.com More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
