So far it has been tested only on a Jetson TK1. Patch 1: Removes the old EMC clock, that was unused and not functional Patch 2: Documents bindings for the new long-ram-code property Patch 3: Adds API for reading the ram code Patches 4 to 6: Document OF additions Patch 7: Adds EMC node to Tegra124 DT Patch 8: Adds timings for Jetson TK1 board Patch 9: Adds functions to the MC driver so the EMC driver can stay within its own registers Patch 10: Adds the actual EMC driver, making use of the new MC API Patch 11: Adds EMC clock driver, making use of API provided by the EMC driver Patch 12: Adds debugfs entry for getting and setting the EMC rate Patch 13: On Tegra124, have the EMC clock be the parent of the MC clock Regards, Tomeu [0] https://github.com/thierryreding/linux/commits/staging/iommu [1] http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=emc-v3 Mikko Perttunen (9): clk: tegra124: Remove old emc clock soc/tegra: Add ram code reader helper of: Add Tegra124 EMC bindings ARM: tegra: Add EMC to Tegra124 device tree ARM: tegra: Add EMC timings to Jetson TK1 device tree memory: tegra: Add API needed by the EMC driver memory: tegra: Add EMC (external memory controller) driver clk: tegra: Add EMC clock driver memory: tegra: Add debugfs entry for getting and setting the EMC rate Tomeu Vizoso (4): of: Document long-ram-code property in nvidia,tegra20-apbmisc of: document new emc-timings subnode in nvidia,tegra124-car of: Document timings subnode of nvidia,tegra-mc clk: tegra: Set the EMC clock as the parent of the MC clock .../bindings/clock/nvidia,tegra124-car.txt | 46 +- .../memory-controllers/nvidia,tegra-mc.txt | 46 +- .../bindings/memory-controllers/tegra-emc.txt | 118 + .../bindings/misc/nvidia,tegra20-apbmisc.txt | 2 + arch/arm/boot/dts/tegra124-jetson-tk1-emc.dtsi | 2412 ++++++++++++++++++++ arch/arm/boot/dts/tegra124-jetson-tk1.dts | 2 + arch/arm/boot/dts/tegra124.dtsi | 7 + drivers/clk/tegra/Makefile | 2 +- drivers/clk/tegra/clk-divider.c | 2 +- drivers/clk/tegra/clk-emc.c | 470 ++++ drivers/clk/tegra/clk-tegra124.c | 18 +- drivers/clk/tegra/clk.h | 2 + drivers/memory/Kconfig | 10 + drivers/memory/Makefile | 1 - drivers/memory/tegra/Makefile | 1 + drivers/memory/tegra/tegra-mc.c | 172 ++ drivers/memory/tegra/tegra124-emc.c | 1169 ++++++++++ drivers/soc/tegra/fuse/tegra-apbmisc.c | 19 + include/soc/tegra/fuse.h | 1 + include/soc/tegra/memory.h | 19 + 20 files changed, 4498 insertions(+), 21 deletions(-) create mode 100644 Documentation/devicetree/bindings/memory-controllers/tegra-emc.txt create mode 100644 arch/arm/boot/dts/tegra124-jetson-tk1-emc.dtsi create mode 100644 drivers/clk/tegra/clk-emc.c create mode 100644 drivers/memory/tegra/tegra124-emc.c create mode 100644 include/soc/tegra/memory.h -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
