iommu/tegra-smmu: Parameterize number of TLB lines (2015-08-13 17:05:28 +0200)
This is the pull request with Russell's updates. I've added a patch
on top to unbreak Tegra30, which had been broken since the original
rewrite of the SMMU driver.
Thanks,
Thierry

iommu/tegra-smmu: Changes for v4.3-rc1
A bunch of improvements by Russell King, along with a fix to restore
display support when using the SMMU. This was due to the SMMU driver
writing the wrong value of active TLB lines, effectively disabling the
TLB and causing massive underflows on the display controller because
of the latency introduced by the SMMU.
