title: Freescale Layerscape SCFG PCIe MSI controller
|
|
|
|
description: |
|
|
This interrupt controller hardware is a second level interrupt controller that
|
|
is hooked to a parent interrupt controller: e.g: ARM GIC for ARM-based
|
|
platforms. If interrupt-parent is not provided, the default parent interrupt
|
|
controller will be used.
|
|
|
|
Each PCIe node needs to have property msi-parent that points to
|
|
MSI controller node
