Hello,
> Qcom PCIe RC controllers are capable of generating 'global' SPI interrupt
> to the host CPU. This interrupt can be used by the device driver to handle
> PCIe link specific events such as Link up and Link down, which give the
> driver a chance to start bus enumeration on its own when link is up and
> initiate link training if link goes to a bad state. The PCIe driver can
> still work without this interrupt but it will provide a nice user
> experience when device gets plugged and removed.

> Document the interrupt as optional for SM8550 and SM8650 platforms.
Applied to dt-bindings for v6.14, thank you!
