Message-ID: <1390952176-30402-1-git-send-email-pdeschrijver@nvidia.com> Date: Wed, 29 Jan 2014 01:36:10 +0200 From: Peter De Schrijver <pdeschrijver@...dia.com> To: Peter De Schrijver <pdeschrijver@...dia.com> CC: <linux-arm-kernel@...ts.infradead.org>, <linux-tegra@...r.kernel.org>, <linux-kernel@...r.kernel.org> Subject: [PATCH v3 0/6] efuse driver for Tegra This driver allows userspace to read the raw efuse data. Its userspace interface is modelled after the sunxi_sid driver which provides similar functionality for some Allwinner SoCs. It has been tested on Tegra20 (ventana), Tegra30 (beaverboard) and Tegra114 (dalmore). Changes since v1: * Add documentation for sysfs interface * Cleanup messages Changes since v2: * Incorporate early fuse code * Remove module support * Make driver always build when Tegra platform is selected * Add DT binding document * Address comments on v2 TODO: * test on Tegra124 (venice2) Peter De Schrijver (6): ARM: tegra: export apb dma readl/writel ARM: tegra: Add chipid, revision and fuse init misc: fuse: Add efuse driver for Tegra ARM: tegra: Add efuse bindings misc: enable fuse drivers ARM: tegra: remove fuse files from mach-tegra Documentation/ABI/testing/sysfs-driver-tegra-fuse | 8 + .../devicetree/bindings/fuse/fuse-tegra.txt | 32 +++ arch/arm/boot/dts/tegra114.dtsi | 7 + arch/arm/boot/dts/tegra124.dtsi | 7 + arch/arm/boot/dts/tegra20.dtsi | 7 + arch/arm/boot/dts/tegra30.dtsi | 7 + arch/arm/mach-tegra/Makefile | 4 - arch/arm/mach-tegra/apbio.c | 51 ++-- arch/arm/mach-tegra/cpuidle.c | 2 +- arch/arm/mach-tegra/flowctrl.c | 2 +- arch/arm/mach-tegra/fuse.c | 252 ----------------- arch/arm/mach-tegra/fuse.h | 79 ------ arch/arm/mach-tegra/hotplug.c | 2 +- arch/arm/mach-tegra/platsmp.c | 2 +- arch/arm/mach-tegra/pm.c | 2 +- arch/arm/mach-tegra/pmc.c | 2 +- arch/arm/mach-tegra/powergate.c | 2 +- arch/arm/mach-tegra/reset-handler.S | 2 +- arch/arm/mach-tegra/reset.c | 2 +- arch/arm/mach-tegra/sleep-tegra30.S | 2 +- arch/arm/mach-tegra/tegra.c | 2 +- arch/arm/mach-tegra/tegra114_speedo.c | 104 ------- arch/arm/mach-tegra/tegra20_speedo.c | 109 -------- arch/arm/mach-tegra/tegra2_emc.c | 2 +- arch/arm/mach-tegra/tegra30_speedo.c | 292 ------------------- drivers/misc/Makefile | 1 + drivers/misc/fuse/Makefile | 1 + drivers/misc/fuse/tegra/Makefile | 7 + drivers/misc/fuse/tegra/fuse-tegra.c | 228 +++++++++++++++ drivers/misc/fuse/tegra/fuse-tegra20.c | 136 +++++++++ drivers/misc/fuse/tegra/fuse-tegra30.c | 178 ++++++++++++ drivers/misc/fuse/tegra/fuse.h | 82 ++++++ drivers/misc/fuse/tegra/tegra114_speedo.c | 110 ++++++++ drivers/misc/fuse/tegra/tegra124_speedo.c | 164 +++++++++++ drivers/misc/fuse/tegra/tegra20_speedo.c | 110 ++++++++ drivers/misc/fuse/tegra/tegra30_speedo.c | 294 ++++++++++++++++++++ include/linux/tegra-soc.h | 39 +++ 37 files changed, 1461 insertions(+), 872 deletions(-) create mode 100644 Documentation/ABI/testing/sysfs-driver-tegra-fuse create mode 100644 Documentation/devicetree/bindings/fuse/fuse-tegra.txt delete mode 100644 arch/arm/mach-tegra/fuse.c delete mode 100644 arch/arm/mach-tegra/fuse.h delete mode 100644 arch/arm/mach-tegra/tegra114_speedo.c delete mode 100644 arch/arm/mach-tegra/tegra20_speedo.c delete mode 100644 arch/arm/mach-tegra/tegra30_speedo.c create mode 100644 drivers/misc/fuse/Makefile create mode 100644 drivers/misc/fuse/tegra/Makefile create mode 100644 drivers/misc/fuse/tegra/fuse-tegra.c create mode 100644 drivers/misc/fuse/tegra/fuse-tegra20.c create mode 100644 drivers/misc/fuse/tegra/fuse-tegra30.c create mode 100644 drivers/misc/fuse/tegra/fuse.h create mode 100644 drivers/misc/fuse/tegra/tegra114_speedo.c create mode 100644 drivers/misc/fuse/tegra/tegra124_speedo.c create mode 100644 drivers/misc/fuse/tegra/tegra20_speedo.c create mode 100644 drivers/misc/fuse/tegra/tegra30_speedo.c -- 1.7.7.rc0.72.g4b5ea.dirty -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
