Hello, because Mikko's internship is over and he's short of time these days, I have taken his patches witht he intention of moving this work forward. 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. The comments from the last review round have been addressed, most notably: - Timings are per-ramcode. - A new property in the DT can cause the whole 4 bits in PMC_STRAPPING_OPT_A_0 [7:4] to be used when decoding the ram code, allowing for a single board to support more ram configurations. - Each driver accesses only its own registers, so API has been added so each driver can delegate on the others. - Usage of debugfs for setting the clock rate of the EMC clock has been split in its own commit in case it's still controversial. Patch 1: Removes clocks that are unused because of not being fully functional Patch 2: Documents bindings for the new long-ram-code property Patch 3: Adds API for reading the ram code Patch 4: Adds bindings for the EMC node Patch 5: Adds EMC node to Tegra124 DT Patch 6: Adds timings for Jetson TK1 board Patch 7: Adds functions to the MC driver so the EMC driver can stay within its own registers Patch 8: Adds the actual EMC driver, making use of the new MC API Patch 9: Adds EMC clock driver, making use of API provided by the EMC driver Patch 10: Adds debugfs entry for getting and setting the EMC rate Regards, Tomeu [0] https://github.com/thierryreding/linux/commits/staging/iommu [1] http://cgit.collabora.com/git/user/tomeu/linux.git/log/?h=emc Mikko Perttunen (8): clk: tegra124: Remove old emc_mux and emc clocks 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 Tomeu Vizoso (2): soc/tegra: Document long-ram-code property in nvidia,tegra20-apbmisc memory: tegra: Add debugfs entry for getting and setting the EMC rate .../bindings/memory-controllers/tegra-emc.txt | 41 + .../bindings/misc/nvidia,tegra20-apbmisc.txt | 3 + 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-emc.c | 449 ++++ drivers/clk/tegra/clk-tegra124.c | 13 +- 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 | 1164 ++++++++++ drivers/soc/tegra/fuse/tegra-apbmisc.c | 19 + include/soc/tegra/fuse.h | 1 + include/soc/tegra/memory.h | 19 + 17 files changed, 4304 insertions(+), 14 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 devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
