From: Thierry Reding <treding@xxxxxxxxxx> Hi, this puts together the two patches from this thread: http://patchwork.ozlabs.org/patch/1146705/ there hasn't been any activity there for a couple of weeks, so I thought I'd just throw them together and update the second patch to work on top of the first one. The goal here is to avoid the use of bounce buffers and fix IOVA space issues when an IOMMU gets involved. The first patch introduces the ->set_dma_mask() host operation as proposed by Adrian and the second patch is just a rebase of Nicolin's Tegra SDHCI patch that uses the new host operation rather than doing it as part of ->enable_dma().
