[PATCHv4 1/4] drivers: tee: i2c trampoline driver
This commit gives the secure world access to the I2C bus so it can communicate with I2C slaves (typically those would be secure elements like the NXP SE050).
A similar service implementation has been merged in linux: c05210ab ("drivers: optee: allow op-tee to access devices on the i2c bus")
