5.10.110-rockchip-rk3588

Any idea?

[astsam]

Check the 5.10-compat branch (67adfa1). The driver is compiled successfully but I am not sure it is 100% functional.

Thanks, but now getting a new error (take into account this kernel is very hacked by rockchip)

[astsam]

As a quick workaround disable support for mt76x0e, mt76x2e, mt7603e, mt7615e chips.

[blackenz]

I tried to disable support for the devices @astsam referred on the 5.10-compat branch but i'm also struggling to compile the module.
I get this error:

Any advices?
Thanks You

Any news on this? Would love to have this running on nvidia jetson, the kernel is pinned at 5.10 for the latest release.

Seems like OpenWRT 22.03 backported this for kernel 5.10, can't we reuse that one?

Or can we maybe use / merge it here: https://cdn.kernel.org/pub/linux/kernel/projects/backports/stable/ ?

Hello, I have a very similar situation, I need to install mt7921u driver on nvidia jetson, have you successfully installed this? I would appreciate it if you could give me any tips!
