Non volatile memory area is available on STM32. It contains various factory programmed information such as unique device ID, analog calibration... This patchset adds: - NVMEM support to access stm32 data cells - helper to read 16 bits cells. --- Changes in v2: - update "st,stm32f4-otp" compatible as discussed with Rob - add stm32f429 dts - add core helper to read 16 bits cells Fabrice Gasnier (6): dt-bindings: nvmem: Add STM32 factory-programmed romem nvmem: Add driver for STM32 factory-programmed read only mem nvmem: stm32: add support for STM32MP15 BSEC to control OTP data nvmem: core: add nvmem_cell_read_u16 ARM: dts: stm32: Add romem and temperature calibration on stm32mp157c ARM: dts: stm32: Add romem and temperature calibration on stm32f429 .../devicetree/bindings/nvmem/st,stm32-romem.txt | 31 ++++ arch/arm/boot/dts/stm32f429.dtsi | 13 ++ arch/arm/boot/dts/stm32mp157c.dtsi | 13 ++ drivers/nvmem/Kconfig | 10 + drivers/nvmem/Makefile | 2 + drivers/nvmem/core.c | 37 ++++ drivers/nvmem/stm32-romem.c | 202 +++++++++++++++++++++ include/linux/nvmem-consumer.h | 7 + 8 files changed, 315 insertions(+) create mode 100644 Documentation/devicetree/bindings/nvmem/st,stm32-romem.txt create mode 100644 drivers/nvmem/stm32-romem.c -- 2.7.4
