Hello, this v7 rebases on top of v4.0-rc1 and contains the following changes: * Removes registers from the burst blocks that were redundant * Removes nvidia,emc-cfg-dig-dll as it is unused in T124 * Adds timings for the Nyan Big and Blaze boards * Disables the ARBITRATION_EMEM interrupt, as it can be very disruptive when the EMC clock runs at low frequencies and shouldn't probably be enabled in any case in a production kernel as it's intended to be used as a development tool * I have tested it on the Nyan boards, in addition to the 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: Exposes clk_hw_reparent function Patch 13: Adds EMC clock driver, making use of API provided by the EMC driver Patch 14: Adds debugfs entry for getting and setting the EMC rate Patch 15: On Tegra124, have the EMC clock be the parent of the MC clock Patches 16 and 17: Add timings for the Nyan Big and Blaze boards Patches 18: Disables ARBITRATION_EMEM http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=emc-v7 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 (9): 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 ARM: tegra: Add EMC timings to Nyan Big device tree ARM: tegra: Add EMC timings to Nyan Blaze device tree memory: tegra: Disable ARBITRATION_EMEM interrupt .../bindings/clock/nvidia,tegra124-car.txt | 44 +- .../memory-controllers/nvidia,tegra-mc.txt | 84 +- .../bindings/memory-controllers/tegra-emc.txt | 374 +++ .../bindings/misc/nvidia,tegra20-apbmisc.txt | 2 + arch/arm/boot/dts/tegra124-jetson-tk1-emc.dtsi | 2421 ++++++++++++++++++++ arch/arm/boot/dts/tegra124-jetson-tk1.dts | 4 + arch/arm/boot/dts/tegra124-nyan-big-emc.dtsi | 2023 ++++++++++++++++ arch/arm/boot/dts/tegra124-nyan-big.dts | 2 + arch/arm/boot/dts/tegra124-nyan-blaze-emc.dtsi | 2049 +++++++++++++++++ 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 | 140 +- drivers/memory/tegra/tegra124-emc.c | 1165 ++++++++++ drivers/memory/tegra/tegra124.c | 44 + drivers/soc/tegra/fuse/tegra-apbmisc.c | 21 + include/linux/clk-provider.h | 1 + include/soc/tegra/emc.h | 19 + include/soc/tegra/fuse.h | 1 + include/soc/tegra/mc.h | 14 +- 25 files changed, 8967 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 arch/arm/boot/dts/tegra124-nyan-big-emc.dtsi create mode 100644 arch/arm/boot/dts/tegra124-nyan-blaze-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 -- 2.1.0 -- 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
