I've applied it:

https://git.kernel.org/pub/scm/linux/kernel/git/bmc/linux.git/commit/?h=aspeed/arm/dt&id=f28674fab34f07fff9612c3f390d3699bfe8ed90

It will be part of v6.20 (via pull-request to the SoC tree).

Send patches based on the bmc tree's aspeed/arm/dt branch (i.e. the
branch containing the commit linked above). Your work is going to land
there anyway, so no need to strictly base your work on Linus' master
branch (though this is generally reasonable when there are no other
dependencies).
