With this patch applied in the mainline kernel, the qemu xlnx-zcu102
emulation crashes (see below). Any idea what it might take to get
qemu back to working ?
Driver talks through ATF to PMU unit(microblaze). I don't think A53+MB
concept is working with mainline qemu. But crash is too hard. It should
be no response from PMU and then this panic.

Isn't that a bit harsh too ? Normally one would print an error message
and abort driver instantiation.
It sounds like you are saying that qemu's xlnx-zcu102 emulation is
no longer supported and expected to crash the kernel. Is this a
correct assumption ? If so, I'll drop it from my list of tests.
Thanks,
