   13   The Apple PCIe host controller is a PCIe host controller with
   14   multiple root ports present in Apple ARM SoC platforms, including
   15   various iPhone and iPad devices and the "Apple Silicon" Macs.
   16   The controller incorporates Synopsys DesigWare PCIe logic to
   17   implements its root ports.  But the ATU found on most DesignWare
   18   PCIe host bridges is absent.
   19 
   20   All root ports share a single ECAM space, but separate GPIOs are
   21   used to take the PCI devices on those ports out of reset.  Therefore
   22   the standard "reset-gpios" and "max-link-speed" properties appear on
   23   the child nodes that represent the PCI bridges that correspond to
   24   the individual root ports.
   25 
   26   MSIs are handled by the PCIe controller and translated into regular
   27   interrupts.  A range of 32 MSIs is provided.  These 32 MSIs can be
   28   distributed over the root ports as the OS sees fit by programming
   29   the PCIe controller's port registers.
