-From: "chuanjia.liu" <Chuanjia.Liu@mediatek.com>
-
-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.
