[PATCH v3 0/7] firmware: imx: NXP Edgelock Enclave MUAP Driver

[Pankaj Gupta]

v3 Changes:
- update the commit message for documentation.
- Fixed dt-binding checking error for file- fsl,ele_mu.yaml
- Coverity fixes in the ele_mu.c

v2 Changes:

- Fixed Kernel Test Bot issues.
- Removed ".../devicetree/bindings/mailbox/fsl,muap.txt"

v1:

The Messaging Unit module enables two processing elements within the SoC to
communicate and coordinate by passing messages (e.g., data, status and control)
through its interfaces.

The NXP i.MX EdgeLock Enclave Message Unit (ELE-MUAP) is specifically targeted
for use between application core and Edgelocke Enclave. It allows to send
messages to the EL Enclave using a shared mailbox.

Patch-set add the ELE-MU  kernel driver for exchanging messages with i.MX NXP
ELE IP; both from:
- User-Space Applications via character driver.
- Kernel-space, used by kernel management layers like DM-Crypt.
