[PATCHv8] drivers: optee: allow op-tee to access devices on the i2c bus

2020-08-12 Thread Jorge Ramirez-Ortiz
Some secure elements like NXP's SE050 sit on I2C buses. For OP-TEE to control this type of cryptographic devices it needs coordinated access to the bus, so collisions and RUNTIME_PM dont get in the way. This trampoline driver allow OP-TEE to access them. Signed-off-by: Jorge Ramirez-Ortiz --- v
