└─>Freescale i.MX6/7/8 PCIe controller (host mode)
In linux kernel since version 6.3 (release Date: 2023-04-23)  
Enables support for the PCIe controller in the i.MX SoCs to
work in Root Complex mode. The PCI controller on i.MX is based
on DesignWare hardware and therefore the driver re-uses the
DesignWare core functions to implement the driver.
