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. Thanks, Maxime 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 (7): 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 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 | 29 + 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 | 979 +++++++++++++++++++++ 14 files changed, 1400 insertions(+), 193 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 -- 1.9.0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
