Unfortunately, this causes the VOP2 driver to hang my CPU on the first
MMIO access, unless I move it back to late_initcall level.
I added *_ensure_probed for the Rockchip I/O domain device, but this
didn't help and I am not sure where exactly (device dependency? timing?)
the problem is. Any ideas?
Thanks,
