[PATCHv4 0/7] Unifying SMMU driver among Tegra SoCs

[Hiroshi Doyu]

Hi,

This series provides:

(1) Unified SMMU driver among Tegra SoCs
(2) Multiple Address Space support(MASID) in IOMMU(SMMMU)
(3) Tegra IOMMU'able devices, most of platform devices are IOMMU'able.

There's been some discussion[1] about device population order, and I
added a IOMMU hook in driver core:

  [PATCHv4 2/7] driver/core: Populate IOMMU'able devices in order

which is based on the following RFC patch:

  [RFC][PATCHv3+ 1/2] driver/core: Add of_iommu_attach()
  http://lists.linuxfoundation.org/pipermail/iommu/2013-November/006914.html

Tested IOMMU functionality with T30 SD/MMC. Any further testing with
T114 and/or other devices would be really appreciated.

v4:
Add a hook in driver core to control device populatin order.
Introduced arm,smmu "mmu-master" binding instead of tegra own.
Removed DT patches from this series.

v3:
Updated based on Stephen Warren's feedback

v2:
Updated based on Thierry Reding's and Stephen Warren's feedback

v2: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-July/181888.html
v1: http://lists.infradead.org/pipermail/linux-arm-kernel/2013-June/180267.html
