The ACPI and ACPI IORT specifications were updated to support bindings
required to describe GICv5 based systems.

The ACPI specification GICv5 bindings ECR [1] were approved and the
required changes merged in the ACPICA upstream repository[5].

The Arm IORT specification [2] has been updated to include GICv5 IWB
specific bindings in revision E.g.

Implement kernel code that - based on the aforementioned bindings - adds
support for GICv5 ACPI probing.

ACPICA changes supporting the bindings are posted with the series; they
were cherry-picked from the upcoming ACPICA Linuxised release patches
and they should _not_ be merged in any upstream branch because the
full set of Linuxised ACPICA changes will be subsequently posted in
order to be merged, I added the two ACPICA patches to make the series
self-contained.

The patches in question have been included in this series:

https://lore.kernel.org/linux-acpi/12822121.O9o76ZdvQC@rafael.j.wysocki/ (local)

and are going to be applied shortly.

Thanks!
