Linux OP-TEE Driver for Linux 4.14.98 and OP-TEE 3.13

[DevendraDevadiga]

Dear Team,
I am working on Android 9.0 (Pie) where Linux kernel version used is 4.14.98. Along with Android we are planning to use OPTEE 3.13.
So please can you refer me the source code of Linux OP-TEE Driver for Linux version 4.14.98 and OP-TEE version 3.13?
We are working on Armv8 (i.MX8MQ), so Arm-Trusted-Firmware also used (2.0). Is there any dependency is there on the ATF version for using OP-TEE 3.13?

Thanks and Regards,
Devendra

You can find that in the upstream kernel. You may need to cherry-pick some patches from later kernels
You'll get a list to start from with:
git log --oneline --no-merges v5.13 -- drivers/tee include/linux/tee_drv.h include/uapi/linux/tee.h

and OP-TEE version 3.13?

Surely you know where to find that.

Version 2.0 might be a bit old, but it may just work also.
