Sorry, I misread you. This patch was made against mainline 4.0-rc7, not the Raspberry Pi repo. I then used the bcm2835-mmc driver in mainline to be able to test the functionality.

From my point of view, the mmc driver is a discussion of it's own. This patch provides functionality that other drivers can make use of as well. Martin Sperl will soon start working on DMA support for spi-bcm2835, relying on this patch to make that happen.
