Hi all
I have now able to pack those combination and all of them look ok
mainline uboot
optee 3.15.0
atf 2.5
mainline kernel
mainline uboot
optee 3.15.0
imx-atf rel_imx_5.4.70_2.3.2
Linux rel_imx_5.4.70_2.3.2
I have a setup where I can test some peripherals. I can run an optee test on both combinations The big issue I have it's the DSIM display it's not working and crashes the kernel using the rel_imx_5.4.70_2.3.2 nxp version. The mipi randomly deadlock the booting. If I don't register the mipi part it's ok. Can someone have an idea?
Are you using the Linux rel_imx_5.4.70_2.3.2 with imx-atf rel_imx_5.4.70_2.3.2?
The NXP kernel expects the NXP ATF code. The power-domain drivers in the NXP branch make secure calls to ATF which enable/disable the power-domains which control a bunch of peripherals like DSI, CSI, USB and GPU. If you're using the mainline ATF, I don't believe it contains the power-domain controllers, so when the Linux power-domain drivers make the secure calls, it's likely the power-domains won't change.
- mainline uboot
- optee 3.15.0
- imx-atf rel_imx_5.4.70_2.3.2
- Linux rel_imx_5.4.70_2.3.2
I have tried even to not load optee in the image but still the same

All of them can be test using a buildroot setup

Michael,
I have not bothered with NXP's kernel, but I do have DSIM working on 5.15 with a set of patches here https://github.com/Gateworks/linux-venice if it is helpful. I've been using this with a mainline U-Boot, imx-atf lf_v2.4.
I can not boot with lf_v2.4 but I can with atf 2.5
