Converience for reviewer, and past previous discission here. "This is just *wrong*. You cannot hardcode the MMIO address in the driver. Even though this code is old, you should fix it instead of building on top of it. - Mani" IMX7D here is wrong athough check IMX8MQ_PCIE2_BASE_ADDR is not good method. Previously try to use 'linux,pci-domain' to replace this check logic. Need more discussion to improve it and keep old compatiblity. Let's fix this code error firstly.
