Subject: [PATCH v4 1/3] dt-bindings: PCI: imx6q-pcie: Add intr, aer and pme interrupts
Date: Wed, 13 May 2026 10:50:59 +0800 [thread overview]
Message-ID: <20260513025101.1498104-2-hongxing.zhu@nxp.com> (raw)
In-Reply-To: <20260513025101.1498104-1-hongxing.zhu@nxp.com>
Add optional interrupt entries to the i.MX6Q PCIe binding to support
event-based interrupt handling:
- intr: General controller events and link state changes
- aer: Advanced Error Reporting events
- pme: Power Management Events
These interrupts enable proper handling of AER, PME, and other
controller-specific events when supported by the hardware.
