Subject: [PATCH 0/3] dra7xx: PCIe IRQ handling rework

This series re-works dra7xx MSI IRQ handler to avoid issues of missing
of MSI IRQs and Legacy IRQs.

Tested on AM572 EVM with TUSB PCIe USB card and Intel PCIe WiFi cards.

Vignesh R (3):
  Revert "PCI: dwc: Clear MSI interrupt status after it is handled, not
    before"
  PCI: dwc: pci-dra7xx: Improve MSI IRQ handling
  PCI: dwc: pci-dra7xx: Handle legacy and MSI IRQs together
