Hi, Here is the bcm2835-sdhost driver. Patches 1+2 are unmodified from Eric, patches 3+4 are incremental fixes. Left them separate for now, to make it easier to review, should probably squashed in for the final version. Patch 5 adds it to the device tree, in disabled state. Actually enabling the thing depends on a bunch of changes in the gpio handling of the device tree. Leaving that for another day ...
Why did you post this?
See patch 2/5: <quote> The 2835 has two SD controllers: The Arasan SDHCI controller that we currently use, and a custom SD controller. The custom one runs faster </quote>
I think you should be adopting sdhci-iproc - in case there are issues with its bcm2835 support, right!?
sdhci-iproc drives the sdhci controller just fine, the new driver is for the custom controller. On the rpi3 you can even use both in parallel, with the sdcard handled via custom sd controller and the wifi handled by sdhci-iproc. cheers, Gerd
