title: Phytium INTx interrupt controller (IXIC)
|
|
|
|
description: |
|
|
This is a psuedo interrupt controller to handle PCI legacy interrupt on
|
|
Phytium D2000 and FT-2000/4C SoC, which sits between the PCI INTx devices
|
|
and the GIC and forwards the 4 INTx input signals to 4 adjacent GICv3 SPIs.
