Subject: LoongArch: Update dts for Loongson-2K2000 to support PCI-MSI
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=84892cebdc7fd5d6d70ba5b667a7440dfed2d032;p=linux.git

LoongArch: Update dts for Loongson-2K2000 to support PCI-MSI

Current dts file for Loongson-2K2000 misses the interrupt-controller &
interrupt-cells descriptions in the msi-controller node, and misses the
msi-parent link in the pci root node. Add them to support PCI-MSI.
