[PATCH 0/4] irqchip/sg2042-msi: Fix broken affinity setting

[Inochi Amaoto <inochiama@gmail.com>]

When using NVME on SG2044, the NVME always complains "I/O tag XXX
(XXX) QID XX timeout, completion polled", which is caused by the
broken handler of the sg2042-msi driver.

As PLIC driver can only setting affinity when enabling, the sg2042-msi
does not properly handled affinity setting previously and enable irq in
an unexpected executing path.

Add irq_startup/irq_shutdown support to the PCI template domain,
then set irq_chip_[startup/shutdown]_parent for irq_startup/
irq_shutdown of the sg2042-msi driver. So the irq can be started
properly.

Inochi Amaoto (4):
  genirq: Add irq_chip_(startup/shutdown)_parent
  PCI/MSI: Add startup/shutdown support for per device MSI[X] domains
  irqchip/sg2042-msi: Fix broken affinity setting
  irqchip/sg2042-msi: Set MSI_FLAG_MULTI_PCI_MSI flags for SG2044
