I thought I had applied it, but I am mistaken.

It's now applied to the aspeed tree for v5.16. I made one small fix to

It will appear in the next linux-next, and in v5.16 once the merge window opens.

Cheers,

Joel

Argh, I'm sorry for that! Did I miss to run a test that would have
complained about this?

Perfect, thank you!

Thank you! Just in case and since I just looked for it for a bit: The
"aspeed tree" now seems to be
https://git.kernel.org/pub/scm/linux/kernel/git/joel/bmc.git/.

Unfortunately it fails silently.

You could have cleaned your object tree and checked that the dts was
built into a dtb when running "make" (ie, the default rule without
specifying what to build).

Yes, I changed that a while back as I thought I'd start doing combined
aspeed and nuvoton pull requests. I haven't done a nuvoton one since
(no one using those devices seems to want to use them with upstream
kernels), so perhaps I could go back to using just the aspeed tree.
