[PATCH v2 1/3] dt-bindings: PCI: imx6q-pcie: Add intr, aer and pme interrupts

[Richard Zhu]

Add 'intr', 'aer', and 'pme' interrupt entries to the i.MX6Q PCIe
binding to support PCIe event-based interrupts for general controller
events, Advanced Error Reporting, and Power Management Events
respectively.

These interrupts are optional for most variants but required for
fsl,imx95-pcie, which must specify all 5 interrupts (msi, dma, intr,
aer, pme).
