-Subject: [PATCH 32/70] arm64: Add pdev_archdata for dmamask
-
-The dma_mask for a device structure is a pointer. This pointer
-needs to be set up before the dma mask can actually be set. Most
-frameworks in the kernel take care of setting this up properly but
-platform devices that don't follow a regular bus structure may not
-ever have this set. As a result, checks such as dma_capable will
-always return false on a raw platform device and dma_set_mask will
-always return -EIO. Fix this by adding a dma_mask in the
-platform_device archdata and setting it to be the dma_mask. Devices
-used in other frameworks can change this as needed.
