    bool "NVMEM Support"

    help

      Support for NVMEM(Non Volatile Memory) devices like EEPROM, EFUSES...

​

      This framework is designed to provide a generic interface to NVMEM

      from both the Linux Kernel and the userspace.

​

      This driver can also be built as a module. If so, the module

      will be called nvmem_core.

​

      If unsure, say no.

    depends on SYSFS

    default y

    help

     Say Y here to add a sysfs interface for NVMEM.

​

     This interface is mostly used by userspace applications to

     read/write directly into nvmem.

config NVMEM_IMX_IIM

    tristate "i.MX IC Identification Module support"

    depends on ARCH_MXC || COMPILE_TEST

    help

      This is a driver for the IC Identification Module (IIM) available on

      i.MX SoCs, providing access to 4 Kbits of programmable

      eFuses.

​

      This driver can also be built as a module. If so, the module

      will be called nvmem-imx-iim.

    depends on HAS_IOMEM

    help

      This is a driver for the On-Chip OTP Controller (OCOTP) available on

      i.MX6 SoCs, providing access to 4 Kbits of one-time programmable

      eFuses.

​

      This driver can also be built as a module. If so, the module

      will be called nvmem-imx-ocotp.

    tristate "NXP LPC18XX EEPROM Memory Support"

    depends on ARCH_LPC18XX || COMPILE_TEST

    depends on HAS_IOMEM

    help

      Say Y here to include support for NXP LPC18xx EEPROM memory found in

      NXP LPC185x/3x and LPC435x/3x/2x/1x devices.

      To compile this driver as a module, choose M here: the module

      will be called nvmem_lpc18xx_eeprom.

​

config NVMEM_LPC18XX_OTP

    tristate "NXP LPC18XX OTP Memory Support"

    depends on ARCH_LPC18XX || COMPILE_TEST

    depends on HAS_IOMEM

    help

      Say Y here to include support for NXP LPC18xx OTP memory found on

      all LPC18xx and LPC43xx devices.

      To compile this driver as a module, choose M here: the module

      will be called nvmem_lpc18xx_otp.

config NVMEM_MXS_OCOTP

    tristate "Freescale MXS On-Chip OTP Memory Support"

    depends on ARCH_MXS || COMPILE_TEST

    depends on HAS_IOMEM

    help

      If you say Y here, you will get readonly access to the

      One Time Programmable memory pages that are stored

      on the Freescale i.MX23/i.MX28 processor.

​

      This driver can also be built as a module. If so, the module

      will be called nvmem-mxs-ocotp.

config MTK_EFUSE

    tristate "Mediatek SoCs EFUSE support"

    depends on ARCH_MEDIATEK || COMPILE_TEST

    depends on HAS_IOMEM

    help

      This is a driver to access hardware related data like sensor

      calibration, HDMI impedance etc.

​

      This driver can also be built as a module. If so, the module

      will be called efuse-mtk.
