The 2835 has two SD controllers: The Arasan sdhci controller (supported by the iproc driver) and a custom sdhost controller. This patch adds a driver for the latter. The sdhci controller supports both sdcard and sdio. The sdhost controller supports the sdcard only, but has better performance. Also note that the rpi3 has sdio wifi, so driving the sdcard with the sdhost controller allows to use the sdhci controller for wifi support. The configuration is done by devicetree via pin muxing. Both SD controller are available on the same pins (2 pin groups = pin 22 to 27 + pin 48 to 53). So it's possible to use both SD controllers at the same time with different pin groups. The code was originally written by Phil Elwell in the downstream Rasbperry Pi tree. In preparation for the upstream merge it was cleaned up and the code base was moderized by Eric Anholt, Stefan Wahren and Gerd Hoffmann.
