Subject: [PATCH v2 0/2] mmc: sdhci: Set DMA mask if specified
Date: Tue, 1 Mar 2016 13:32:42 +0900 [thread overview]
Message-ID: <1456806764-16467-1-git-send-email-acourbot@nvidia.com> (raw)
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
