nvmem: Add a simple NVMEM framework for nvmem providers This patch adds just providers part of the framework just to enable easy review. Up until now, NVMEM drivers like eeprom were stored in drivers/misc, where they all had to duplicate pretty much the same code to register a sysfs file, allow in-kernel users to access the content of the devices they were driving, etc. This was also a problem as far as other in-kernel users were involved, since the solutions used were pretty much different from on driver to another, there was a rather big abstraction leak. This introduction of this framework aims at solving this. It also introduces DT representation for consumer devices to go get the data they require (MAC Addresses, SoC/Revision ID, part numbers, and so on) from the nvmems. Having regmap interface to this framework would give much better abstraction for nvmems on different buses.

nvmem: disallow modular CONFIG_NVMEM The new of_get_nvmem_mac_address() helper function causes a link error with CONFIG_NVMEM=m: drivers/of/of_net.o: In function `of_get_nvmem_mac_address': of_net.c:(.text+0x168): undefined reference to `of_nvmem_cell_get' of_net.c:(.text+0x19c): undefined reference to `nvmem_cell_read' of_net.c:(.text+0x1a8): undefined reference to `nvmem_cell_put' I could not come up with a good solution for this, as the code is always built-in. Using an #if IS_REACHABLE() check around it would solve the link time issue but then stop it from working in that configuration. Making of_nvmem_cell_get() an inline function could also solve that, but seems a bit ugly since it's somewhat larger than most inline functions, and it would just bring that problem into the callers. Splitting the function into a separate file might be an alternative. This uses the big hammer by making CONFIG_NVMEM itself a 'bool' symbol, which avoids the problem entirely but makes the vmlinux larger for anyone that might use NVMEM support but doesn't need it built-in otherwise.

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.

nvmem: core: add NVMEM_SYSFS Kconfig Many nvmem providers are not very keen on having default sysfs nvmem entry, as most of the usecases for them are inside kernel itself. And in some cases read/writes to some areas in nvmem are restricted and trapped at secure monitor level, so accessing them from userspace would result in board reboots. This patch adds new NVMEM_SYSFS Kconfig to make binary sysfs entry an optional one. This provision will give more flexibility to users. This patch also moves existing sysfs code to a new file so that its not compiled in when its not really required.

nvmem: Add driver for the i.MX IIM This adds a readonly nvmem driver for the i.MX IC Identification Module (IIM). The IIM is found on the older i.MX SoCs like the i.MX25, i.MX27, i.MX31, i.MX35, i.MX51 and the i.MX53. The IIM can control up to 8 fuse banks with 256 bit each. Not all of the banks are equipped on the different SoCs. The actual number of fuses differ from 512 on the i.MX27 and 1152 on the i.MX53. The fuses are one time writable, but writing is currently not supported in the driver.
