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. .../bindings/mmc/brcm,bcm2835-sdhost.txt | 25 + arch/arm/boot/dts/bcm2835-rpi.dtsi | 10 +- arch/arm/boot/dts/bcm283x.dtsi | 8 + drivers/mmc/host/Kconfig | 9 + drivers/mmc/host/Makefile | 1 + drivers/mmc/host/bcm2835-sdhost.c | 1652 ++++++++++++++++++++ 6 files changed, 1704 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mmc/brcm,bcm2835-sdhost.txt create mode 100644 drivers/mmc/host/bcm2835-sdhost.c -- 2.7.0 -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
