Subject: [PATCH v5 0/8] Introduce automatic DMA configuration for IOMMU masters
Date: Fri, 28 Nov 2014 13:29:38 +0000 [thread overview]
Message-ID: <1417181386-18142-1-git-send-email-will.deacon@arm.com> (raw)
Hi all,
Here is v5 of the patches I've previously sent here:
RFCv1: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/283023.html
RFCv2: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/283752.html
RFCv3: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/287031.html
RFCv4: http://lists.infradead.org/pipermail/linux-arm-kernel/2014-November/302711.html
Changes since RFCv4 include:
- Dropped the RFC tag, since has been used by a couple of people now
- Dropped the DMA segment configuration from of_dma_configure, as there
appear to be assumptions about 64k segments elsewhere in the kernel
- Added acks/tested-bys (thanks to everybody who reviewed the series)
- A few small fixes for issues found by Marek
Arnd: Is this too late for 3.19? We could merge the first 6 patches
with no issues, since there aren't any callers of of_iommu_init
without patch 7 anyway.
Up to you.
Will

Marek Szyprowski (1):
iommu: fix initialization without 'add_device' callback
Will Deacon (7):
iommu: provide early initialisation hook for IOMMU drivers
dma-mapping: replace set_arch_dma_coherent_ops with arch_setup_dma_ops
iommu: add new iommu_ops callback for adding an OF device
iommu: provide helper function to configure an IOMMU for an of master
dma-mapping: detect and configure IOMMU in of_dma_configure
arm: call iommu_init before of_platform_populate
arm: dma-mapping: plumb our iommu mapping ops into arch_setup_dma_ops
