nvmem: imx-ocotp: Fix wrong register size

2017-08-07T01:59:48Z

[ Upstream commit 14ba972842f9e84e6d3264bc0302101b8a792288 ] All i.MX6 SoCs have an OCOTP Controller with 4kbit fuses. The i.MX6SL is an exception and has only 2kbit fuses. In the TRM for the i.MX6DQ (IMX6QDRM - Rev 2, 06/2014) the fuses size is described in chapter 46.1.1 with: "32-bit word restricted program and read to 4Kbits of eFuse OTP(512x8)." In the TRM for the i.MX6SL (IMX6SLRM - Rev 2, 06/2015) the fuses size is described in chapter 34.1.1 with: "32-bit word restricted program and read to 2 kbit of eFuse OTP(128x8)." Since the Freescale Linux kernel OCOTP driver works with a fuses size of 2 kbit for the i.MX6SL, it looks like the TRM is wrong and the formula to calculate the correct fuses size has to be 256x8.

nvmem: core: fix leaks on registration errors

2017-07-21T05:42:22Z

commit 3360acdf839170b612f5b212539694c20e3f16d0 upstream. Make sure to deregister and release the nvmem device and underlying memory on registration errors. Note that the private data must be freed using put_device() once the struct device has been initialised. Also note that there's a related reference leak in the deregistration function as reported by Mika Westerberg which is being fixed separately.

Pull ARM SoC driver updates from Arnd Bergmann: "Driver updates for ARM SoCs, including a couple of newly added drivers: - The Qualcomm external bus interface 2 (EBI2), used in some of their mobile phone chips for connecting flash memory, LCD displays or other peripherals - Secure monitor firmware for Amlogic SoCs, and an NVMEM driver for the EFUSE based on that firmware interface. - Perf support for the AppliedMicro X-Gene performance monitor unit - Reset driver for STMicroelectronics STM32 - Reset driver for SocioNext UniPhier SoCs Aside from these, there are minor updates to SoC-specific bus, clocksource, firmware, pinctrl, reset, rtc and pmic drivers" * tag 'armsoc-drivers' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (50 commits) bus: qcom-ebi2: depend on HAS_IOMEM pinctrl: mvebu: orion5x: Generalise mv88f5181l support for 88f5181 clk: mvebu: Add clk support for the orion5x SoC mv88f5181 dt-bindings: EXYNOS: Add Exynos5433 PMU compatible clocksource: exynos_mct: Add the support for ARM64 perf: xgene: Add APM X-Gene SoC Performance Monitoring Unit driver Documentation: Add documentation for APM X-Gene SoC PMU DTS binding MAINTAINERS: Add entry for APM X-Gene SoC PMU driver bus: qcom: add EBI2 driver bus: qcom: add EBI2 device tree bindings rtc: rtc-pm8xxx: Add support for pm8018 rtc nvmem: amlogic: Add Amlogic Meson EFUSE driver firmware: Amlogic: Add secure monitor driver soc: qcom: smd: Reset rx tail rather than tx memory: atmel-sdramc: fix a possible NULL dereference reset: hi6220: allow to compile test driver on other architectures reset: zynq: add driver Kconfig option reset: sunxi: add driver Kconfig option reset: stm32: add driver Kconfig option reset: socfpga: add driver Kconfig option ...

nvmem: rockchip-efuse: add rk3399-efuse support

2016-09-02T15:22:51Z

1) the efuse timing of rk3399 is different from earlier SoCs. 2) rk3399-efuse is organized as 32bits by 32 one-time programmable electrical fuses, the efuse of earlier SoCs is organized as 32bits by 8 one-time programmable electrical fuses with random access interface. This patch adds a new read function for rk3399-efuse.

nvmem: imx-ocotp: add COMPILE_TEST for proper test coverage

2016-06-25T14:42:55Z

This patch add COMPILE_TEST to imx-ocotp driver so that it can be compile tested on other platforms with zero day testing. Also adds HAS_IOMEM dependancy as the users of devm_ioremap_resource() which are compile-testable should depend on HAS_IOMEM.

Before access ocotp nvmem area, the clock should be enabled. Or, `hexdump nvmem` will hang the system. So, use such flow: " 1. clock_enable_prepare 2. read nvmem ocotp area 3. clock_disable_unprepare " Signed-off-by: Peng Fan Cc: Srinivas Kandagatla Cc: Maxime Ripard Cc: Shawn Guo Signed-off-by: Srinivas Kandagatla Signed-off-by: Greg Kroah-Hartman

nvmem: mxs-ocotp: remove nvmem regmap dependency

2016-06-25T14:42:55Z

Regmap raw accessors are bus specific implementations, using regmap raw apis in nvmem breaks nvmem providers based on regmap mmio. This patch moves to nvmem support in the driver to use callback instead of regmap, which is what the nvmem core supports now.
