+
+There are two independent PCIe controllers in MT2712/MT7622 platform,
+and each of them should contain an independent MSI domain.
+
+In current architecture, MSI domain will be inherited from the root
+bridge, and all of the devices will share the same MSI domain.
+Hence that, the PCIe devices will not work properly if the irq number
+which required is more than 32.
+
+Split the PCIe node for MT2712/MT7622 platform to fix MSI issue and
+comply with the hardware design.

+
+There are two independent PCIe controllers in MT2712/MT7622 platform,
+and each of them should contain an independent MSI domain.
+
+In current architecture, MSI domain will be inherited from the root
+bridge, and all of the devices will share the same MSI domain.
+Hence that, the PCIe devices will not work properly if the irq number
+which required is more than 32.
+
+Split the PCIe node for MT2712/MT7622 platform to fix MSI issue and
+comply with the hardware design.
