Here's a series to enable the SDHOST controller. It gives us better performance than our old sdhci-bcm2835.c. The downstream Raspberry Pi kernel appears to be using this controller by default at this point.
I've tried to do some testing on it (mounting filesystem, reading/writing files, speed tests), but I'm not sure what a good testing regimen for storage drivers would be.
Eric Anholt (4): dt-bindings: Add binding for brcm,bcm2835-sdhost. mmc: bcm2835-sdhost: Add new driver for the internal SD controller. ARM: bcm2835: Include SDHOST in the device tree. ARM: bcm2835: Enable SDHOST by default.
