Hello, in this v5 you can find these changes: * Update EMC data to V5.0.17 version of the DVFS tables * Add struct tegra_emc as a parameter in the EMC API, removing the need for a global pointer. * Also add a reference to the EMC driver to the CAR node, for the EMC clock to use when calling the EMC API. 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. It depends on Thierry's MC patches at [0] and a branch can be found at [1]. 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 Regards, Tomeu [0] https://github.com/thierryreding/linux/commits/staging/iommu [1] http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=emc-v5 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 (5): 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: 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/tegra/Makefile | 2 +- drivers/clk/tegra/clk-emc.c | 532 +++++ 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/soc/tegra/emc.h | 19 + include/soc/tegra/fuse.h | 1 + include/soc/tegra/mc.h | 14 +- 20 files changed, 4934 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
