It connect to GIC with the same IRQ number of INTx IRQ, so it shares the same IRQ with INTx IRQ. This patchset add MSI support for MT2712 and MT7622. Also do some code fixup and cleanups. Change Since V1: - Add the first two patches into this patchset. - Using -ENODEV instead of PTR_ERR if msi_domain == NULL - Change the error logs with consistency of lower-case - Using has_msi instead of support_msi to make the parameter name a bit shorter Honghui Zhang (3): PCI: mediatek: Fix return value in case of error PCI: mediatek: take use of bus->sysdata to get host private data PCI: mediatek: add msi support for MT2712 and MT7622 drivers/pci/host/pcie-mediatek.c | 157 +++++++++++++++++++++++++++++++++++++-- 1 file changed, 151 insertions(+), 6 deletions(-) -- 2.6.4
