Subject: [PATCH v2 0/2] mmc: sdhci: Set DMA mask if specified

Allow host drivers to set the sdhci_host's dma_mask in order to specify the
supported DMA range of a device. Without this, devices that are capable of
64-bit addressing might end up using bounce buffers because the default DMA mask
is 32-bit.

Changes since v1:
- Set the DMA mask in the common code
- Set the capabilities of the various Tegra controllers

Alexandre Courbot (2):
  mmc: sdhci: Set DMA mask
  mmc: sdhci-tegra: Specify valid DMA mask
