The second patch fixup the IRQ handle routine by using irq_chip solution to avoid IRQ reentry which may exist for both MT2712 and MT7622. Change since v6: - Remove the irq_mask, irq_unmask callback in lower layer irq_chip since we have set the MSI_FLAG_USE_DEF_CHIP_OPS flags. - Add irq_ack callback in irq_chip to handle edge IRQ. - Uing handle_edge_irq to handle the MSI IRQs. Change since v5: - Make the comments consistend with the code modification in the first patch. - Using writew to performing a 16-bit write. - Using irq_chip solution to fix the IRQ issue. The v5 patchset could be found in: https://patchwork.kernel.org/patch/10133303 https://patchwork.kernel.org/patch/10133305 Change since v4: - Only setup vendor ID for MT7622, igorning the device ID since mediatek's host bridge driver does not cares about the device ID. Change since v3: - Setup the class type and vendor ID at the beginning of startup instead of in a quirk. - Add mediatek's vendor ID, it could be found in: https://pcisig.com/membership/member-companies?combine=&page=4 Change since v2: - Move the initialize of the iterate before the loop to fix an INTx IRQ issue in the first patch Change since v1: - Add the second patch. - Make the first patch's commit message more standard.
