Subject: [PATCH v8 0/2] Adding support for Versal CPM as Root Port driver
Date: Mon,  8 Jun 2020 18:48:56 +0530	[thread overview]
Message-ID: <1591622338-22652-1-git-send-email-bharat.kumar.gogada@xilinx.com> (raw)

- 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 interrupt line.

Changes for v8:
- Added support for handling error events and INTx interrupts
  separately using nested chained irqchips.
- Added support to free allocated resources in error cases.
