Subject: [PATCH 1/2] iommu/of: Let pci_fixup_final access iommu_fwnode
Date: Tue, 12 May 2020 12:08:30 +0800 [thread overview]
Message-ID: <1589256511-12446-2-git-send-email-zhangfei.gao@linaro.org> (raw)
In-Reply-To: <1589256511-12446-1-git-send-email-zhangfei.gao@linaro.org>
Calling pci_fixup_final after of_pci_iommu_init, which alloc
iommu_fwnode. Some platform devices appear as PCI but are
actually on the AMBA bus, and they need fixup in
drivers/pci/quirks.c handling iommu_fwnode.
So calling pci_fixup_final after iommu_fwnode is allocated.
