Subject: [PATCH 2/2] iommu: calling pci_fixup_iommu in iommu_fwspec_init
Date: Tue, 26 May 2020 19:49:09 +0800 [thread overview]
Message-ID: <1590493749-13823-3-git-send-email-zhangfei.gao@linaro.org> (raw)
In-Reply-To: <1590493749-13823-1-git-send-email-zhangfei.gao@linaro.org>
Calling pci_fixup_iommu in iommu_fwspec_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_iommu after iommu_fwnode is allocated.
