hello,
Thanks very much for analysis. And i have get the cause of the problem.
I will add pl011_allocate_multi_irqs/pl011_release_multi_irqs functions
for amba drivers,
and call them in pl011_startup/pl011_shutdown respectively.
Reserved pl011_allocate_irq/pl011_release_irq functions for platform
drivers.
Please help to confirm, is this ok?

that pl011
binds as a platform driver, *not* an amba driver.
Thanks for pointing out, Robin. I just yet to see an ARM server
booting from DT
those days.
Unlikely in production datacentre/cloud environments, indeed, although
some of the mid-range kit like LX2160 does start to blur the line of
what might be considered "server", and that's one example which *does*
have full-featured DT support (even if it also aspires to ACPI...)
What I thought was worth clarifying for the general audience is that
the relevant aspects of "server" here should in fact still be possible
to reproduce on something like a Raspberry Pi or a tiny QEMU VM, if
one can figure out the ACPI runes :)
Thanks,
Robin.
