[PATCH v2 0/6] Add nvmem support on STM32

[Fabrice Gasnier]

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
