[PATCH 0/3] tee: add MbedTEE driver

[Xing Loong]

This series adds a Linux TEE driver for MbedTEE, a Trusted
Execution Environment for embedded systems
(https://github.com/mbedtee).

Two RPC transports are provided for systems where platform
firmware or board configuration has already established the
REE/TEE separation before Linux boots:

  - ARM/ARM64: SMC calls and GIC SPI notifications (TrustZone)
  - RISC-V: shared-memory ring buffers and IMSIC MSI notifications

The driver implements the TEE subsystem interface (tee_driver_ops)
and provides GlobalPlatform TEE Client API support, dynamic shared
memory registration, and tee-supplicant support for REE filesystem
and RPMB operations.

The series is structured as follows:
  [1/3] dt-bindings: vendor-prefixes: add mbedtee
  [2/3] dt-bindings: firmware: add mbedtee,rpc binding
  [3/3] tee: add MbedTEE driver

Xing Loong (3):
  dt-bindings: vendor-prefixes: add mbedtee
  dt-bindings: firmware: add mbedtee,rpc binding
  tee: add MbedTEE driver
