Subject: [PATCH v2 3/3] PCI: keystone: Allow AM654 PCIe Endpoint to raise MSI-X interrupt
Date: Tue, 25 Feb 2020 13:47:03 +0530 [thread overview]
Message-ID: <20200225081703.8857-4-kishon@ti.com> (raw)
In-Reply-To: <20200225081703.8857-1-kishon@ti.com>
AM654 PCIe EP controller has MSI-X capability register and has the
ability to raise MSI-X interrupt. Add support in pci-keystone.c
for PCIe endpoint controller in AM654 to raise MSI-X interrupts.
