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).
