Hi ARM SoC Team,
Please pull ! As mentioned in tha tag there is one PSCI fix that kept
missing for few months now, so have included it here.

firmware: psci: Fix return value from psci_system_suspend() (2024-06-17 11:02:42 +0100)
----------------------------------------------------------------
Arm FF-A driver updates for v6.11
The main addition is the split of bus and driver into distinct modules
The FF-A bus module is initialized at subsys_initcall level when builtin.
FF-A drivers initialization is now changed to module_init level so that
pKVM ffa proxy is all setup and running in case pKVM hypervisor needs to
trap and handle FF-A calls.
One of the reason for not having this split from the beginning is the
need to workaround the FF-A v1.0 NULL UUID. The FF-A bus layer called
into FF-A driver and populated the device UUID if it matches with the
driver attempting to match. Moving the workaround away from the FF-A
bus layer to the FF-A core driver as a bus notifier will help to remove
the dependency.
Also, there is one fix to handle the return value from psci_system_suspend()
correctly.
