  Hello,

This series adds GIC-ITS support to SM8450 PCIe controllers for receiving
the MSIs from endpoint devices.

The GIC-ITS MSI implementation provides an advantage over internal MSI
implementation using Locality-specific Peripheral Interrupts (LPI) that
would allow MSIs to be targeted for each CPU core.

This series has been tested on SM8450 based dev board that works using an
out-of-tree dts where the MSIs from endpoint devices are distributed across
the CPU cores.

Thanks,
Mani

Changes in v2:

* Swapped the Device ID for PCIe0 as it causes same issue as PCIe1
* Removed the definition of msi-map and msi-map-mask from binding
* Added Ack from Krzysztof
