* AppliedMicro X-Gene v1 PCIe MSI controller
|
|
|
|
Required properties:
|
|
|
|
- compatible: should be "apm,xgene1-msi" to identify
|
|
X-Gene v1 PCIe MSI controller block.
|
|
- msi-controller: indicates that this is an X-Gene v1 PCIe MSI controller node
|
|
- reg: physical base address (0x79000000) and length (0x900000) for controller
|
|
registers. These registers include the MSI termination address and data
|
|
registers as well as the MSI interrupt status registers.
|
|
- reg-names: not required
|
|
- interrupts: A list of 16 interrupt outputs of the controller, starting from
|
|
interrupt number 0x10 to 0x1f.
|
|
- interrupt-names: not required
|
|
|
|
Each PCIe node needs to have property msi-parent that points to an MSI
|
|
controller node
|
|
|
|
Examples:
|
|
|
|
SoC DTSI:
|
|
|
|

|
|
