Subject: [PATCH] arm64: dts: mediatek: Split PCIe node for MT2712 and MT7622
|
|
|
|
There are two independent PCIe controllers in MT2712 and MT7622
|
|
platform. Each of them should contain an independent MSI domain.
|
|
|
|
In old dts 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 and MT7622 platform to comply with
|
|
the hardware design and fix MSI issue.
