iommu/ipmmu-vmsa: r8a7795 support V4
[PATCH v4 01/09] iommu/ipmmu-vmsa: Introduce features, break out alias
[PATCH v4 02/09] iommu/ipmmu-vmsa: Add optional root device feature
[PATCH v4 03/09] iommu/ipmmu-vmsa: Enable multi context support
[PATCH v4 04/09] iommu/ipmmu-vmsa: Make use of IOMMU_OF_DECLARE()
[PATCH v4 05/09] iommu/ipmmu-vmsa: IPMMU device is 40-bit bus master
[PATCH v4 06/09] iommu/ipmmu-vmsa: Write IMCTR twice
[PATCH v4 07/09] iommu/ipmmu-vmsa: Make IMBUSCTR setup optional
[PATCH v4 08/09] iommu/ipmmu-vmsa: Allow two bit SL0
[PATCH v4 09/09] iommu/ipmmu-vmsa: Hook up r8a7795 DT matching code
Here's an updated series for r8a7795 IPMMU support. The patches adjust
the code based on feedback from Geert and Robin together with a rebase
to include changes from the recently posted series:
[PATCH 00/04] iommu/ipmmu-vmsa: 32-bit ARM update
The DT binding for r8a7795 has been accepted for upstream merge
and this series implements support following such format:
d4e42e7 iommu/ipmmu-vmsa: Add r8a7795 DT binding
The r8a7795 IPMMU is almost register compatible with earlier devices
like r8a7790-r8a7794, however some bitfields have been shifted
slightly. On a grander scale topology has been added and interrupts
have been reworked. So now there are several "cache" IPMMU units
without interrupt that somehow communicate with IPMMU-MM that
is the only instance that supports interrupts. The code refers to
IPMMU-MM as a "root" device and the other ones as "leaf" nodes.
Changes since V3:
- Rebased on top of [PATCH 00/04] iommu/ipmmu-vmsa: 32-bit ARM update
- Patch 1/9 has been updated to use of_device_get_match_data(), thanks Robin!
- Patch 2/9 has been reworked to make it easier to follow, thanks Geert!
- Patch 3/9 now uses unsigned int for context counts - thanks Robin!
- Patch 6/9 now includes function name changes - thanks Robin!
- Patch 9/9 now uses dev_err() instead of dev_info() - thanks Geert!
Changes since V2:
- Patch 2/9 has been updated with a bug fix and to supply __ipmmu_find_root()
- Patch 4/9 now makes use of iommu_device_* functions
- Patch 5/9 sets the mask to 40 bits instead of 64 bits
- Patch 9/9 implements white list handling via ->xlate() and fixes a bug
