Hello, this v6 mainly contains a rebase on latest linux-next. There's an outstanding issue with frequencies lower than 102MHz, as the MC IP complains of EMEM arbitration errors when at those frequencies. Any suggestions welcome. The downstream kernels that I have seen ignore those errors, but mainline prints a message out, so it's actually visible even if everything else appears to keep working. 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 7: Document OF additions Patch 8: Adds EMC node to Tegra124 DT Patch 9: Adds timings for Jetson TK1 board Patch 10: Adds functions to the MC driver so the EMC driver can stay within its own registers Patch 11: Adds the actual EMC driver, making use of the new MC API Patch 12: Adds EMC clock driver, making use of API provided by the EMC driver Patch 13: Adds debugfs entry for getting and setting the EMC rate Patch 14: On Tegra124, have the EMC clock be the parent of the MC clock http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=emc-v6 Regards, Tomeu 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 (6): 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 of: document external-memory-controller property in tegra124-car clk: Expose clk_hw_reparent to providers clk: tegra: Set the EMC clock as the parent of the MC clock .../bindings/clock/nvidia,tegra124-car.txt | 44 +- .../memory-controllers/nvidia,tegra-mc.txt | 84 +- .../bindings/memory-controllers/tegra-emc.txt | 379 +++ .../bindings/misc/nvidia,tegra20-apbmisc.txt | 2 + arch/arm/boot/dts/tegra124-jetson-tk1-emc.dtsi | 2469 ++++++++++++++++++++ arch/arm/boot/dts/tegra124-jetson-tk1.dts | 2 + arch/arm/boot/dts/tegra124.dtsi | 8 + drivers/clk/clk.c | 8 + drivers/clk/tegra/Makefile | 2 +- drivers/clk/tegra/clk-emc.c | 528 +++++ drivers/clk/tegra/clk-tegra124.c | 18 +- drivers/clk/tegra/clk.h | 3 + drivers/memory/tegra/Kconfig | 11 + drivers/memory/tegra/Makefile | 2 + drivers/memory/tegra/mc.c | 136 ++ drivers/memory/tegra/tegra124-emc.c | 1164 +++++++++ drivers/memory/tegra/tegra124.c | 44 + drivers/soc/tegra/fuse/tegra-apbmisc.c | 19 + include/linux/clk-provider.h | 1 + include/soc/tegra/emc.h | 19 + include/soc/tegra/fuse.h | 1 + include/soc/tegra/mc.h | 14 +- 22 files changed, 4939 insertions(+), 19 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/emc.h -- 1.9.3 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
