[PATCH v2 0/3] nvmem: stm32: add OP-TEE support for STM32MP13x

[Patrick Delaunay <patrick.delaunay@foss.st.com>]

This serie update the NVMEM BSEC driver to be compatible with STM32MP13x
SoC and the trusted application STM32MP BSEC in OP-TEE

This serie solve issue in initial support of STM32MP131
(using BSEC STM32MP15 compatible) and so it break the STM32MP13x DTS
compatible.

I create this serie for more efficient review, including support for
STM32MP15x.

The first patches of the V1 series is already merged:
"dt-bindings: nvmem: add new stm32mp13 compatible for stm32-romem"

This STM32MP13x DTS break is acceptable as
- the STM32MP13x SoC is not yet available outside STMicroelectronics
  (not official)
- the same patch is already integrated or modifications are in progress in
  the other users (arm-trusted-firmware/TF-A, OP-TEE and U-Boot) of
  stm32mp131 device tree.

It is the good time to correct this issue before the real availability of
the SoC and before full support of STM32MP13x SoC in Linux kernel.

Regards

Patrick

Changes in v2:
- rebase series on linux-next/master
- minor update after V1 revue

Changes in v1:
- update commit message to indicate DTS break reason.
