I am working on several SoCs that also will need this kind of driver
to get entropy from Arm trusted firmware.
If you intend to make this a generic interface, please clean up the
references to MediaTek and give it a more generic name. For example
"Arm Trusted Firmware random number driver".
It will also be helpful if the SMC call number is configurable.
