hw/arm/virt: Use "msi-map" devicetree property for PCI
The "msi-parent" property can be used on the PCI node when MSIs do not contain sideband data (device IDs) [1]. In QEMU, MSI transactions contain the requester ID, so the PCI node should use the "msi-map" property instead of "msi-parent". In our case the property describes an identity map between requester ID and sideband data. This fixes a warning when passing the DTB generated by QEMU to dtc, following a recent change to the GICv3 node: Warning (msi_parent_property): /pcie@10000000:msi-parent: property size (4) too small for cell size 1 [1] linux/Documentation/devicetree/bindings/pci/pci-msi.txt Signed-off-by: Jean-Philippe Brucker <jean-philippe@linaro.org> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Eric Auger <eric.auger@redhat.com> Message-id: 20220927100347.176606-4-jean-philippe@linaro.org Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
