I am currently extending an embedded hardware platform which runs a linux kernel 3.16. I want to connect an external SDIO controller to the USB bus, and then run a WIFI module using that SDIO controller.Since I have only little experience with SDIO devices (I know how to configure eMMC, SD-Card, ... in the device tree), I am unsure about how to proceed if an USB-SDIO-bridge is used.Does such a setup run without any device tree adaption (aka Hey, its USB, let's simply plug it in!), or must I specify the exact location of the SDIO controller in the device tree file?
WIFI over SDIO over USB - Do I have to reflect that in the device tree?
