[PATCH 0/4] bcm2835 SDHOST controller

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.
