Subject: [PATCH 0/6] PAXB INTx support with proper model
Date: Tue, 29 May 2018 14:58:44 -0700 [thread overview]
Message-ID: <1527631130-20045-1-git-send-email-ray.jui@broadcom.com> (raw)
This patch series adds PCIe legacy interrupt (INTx) support to the iProc
PCIe driver by modeling it with its own IRQ domain. All 4 interrupts INTA,
INTB, INTC, INTD share the same interrupt line connected to the GIC
in the system. This is now modeled by using its own IRQ domain.
Also update all relevant devicetree files to adapt to the new model
This patch series is available on GIHUB:
repo: https://github.com/Broadcom/arm64-linux.git
branch: pcie-intx-v1
Ray Jui (6):
PCI: iproc: Update iProc PCI binding for INTx support
PCI: iproc: Add INTx support with better modeling
arm: dts: Change PCIe INTx mapping for Cygnus
arm: dts: Change PCIe INTx mapping for NSP
arm: dts: Change PCIe INTx mapping for HR2
arm64: dts: Change PCIe INTx mapping for NS2
