This is not a direct answer, but I did prepare to step up to 5.11 (https://github.com/jbech-linaro/linux/commits/rpi3-optee-5.11) however, I never got to finalize it. But as you can see, there wasn't a lot of changes. But in theory you're right, doing this is a rebase and just make it work.
Ah, I just realized that I need to use the Raspberry Pi specific Linux trees: https://github.com/raspberrypi/linux/tree/rpi-5.17.y That's also the reason that those files I mentioned didn't exist, as they are not part of mainline Linux.
I guess I would need to use rpi-5.17.y as a base, put the op-tee main branch on top and then cherry-pick the op-tee RPi3 specific commits (from 5.4 branch).

Correct!
I think I succeded.

I can try it out next week and then if OK by you, I can mirror your branch and update the manifest.
Yeah, would be great
Just tested it

So, I'm going to push this branch into the linaro-swg/linux.git
and then send a pull request to the manifest git. Thanks!
Hello!
I need some newer Linux features. However, the current RPi3 supported Linux version for OP-TEE is rpi3-optee-5.4 I need at least 5.14.
It seems that rpi3-optee-5.4 and main are not very different, considering only the "on-top-of-mainline" commits. I thought I might only have to cherry-pick some commits from the rpi3 branch into the main branch. However, it failed already for the first commit ( https://github.com/linaro-swg/linux/commit/196e461df741d8d04f63b4158573f576cd181208 ) because the files
arch/arm/boot/dts/bcm2710-rpi-3-b.dts
andarch/arm/boot/dts/bcm2710.dtsi
are missing. Maybe it's sufficient to only copy this file from the old branch into the new one.But before I dive deeper, I wanted to ask some developers experienced in this matter if my goal is quickly achievable or if there are huge problems I can't see. Thanks!
