[PATCH v6 0/2] Adding support for Versal CPM as Root Port driver

From: Bharat Kumar Gogada
Date: Fri Apr 24 2020 - 08:04:27 EST


- Adding support for Versal CPM as Root port.
- The Versal ACAP devices include CCIX-PCIe Module (CPM). The integrated
block for CPM along with the integrated bridge can function
as PCIe Root Port.
- Versal CPM uses GICv3 ITS feature for assigning MSI/MSI-X
vectors and handling MSI/MSI-X interrupts.
- Bridge error and legacy interrupts in Versal CPM are handled using
Versal CPM specific MISC interrupt line.

Changes for v6:
- Using pci_generic_ecam_ops for ECAM registration.
- Fixed INTX registration handling
