This series implements multiple MSI setup and teardown in terms
of the msichip infrastructure for the designware host controller.
It removes quite a bit of homegrown multi MSI handling from the
driver, which I suspect wasn't really tested before.
The series is currently based on pci/next.
Functionality was tested with an FPGA connected to an i.MX6 SoC.
I have verified that the FPGA is able to trigger the second MSI
and the irq is properly routed into the driver.
Lucas Stach (4):
PCI: allow MSI chip providers to implement their own multiple MSI
setup
PCI: designware: remove bogus multiple MSI setup
PCI: designware: remove open-coded bitmap operations
PCI: designware: implement multiple MSI irq setup
