MMC1 SDIO configuration DTS

General Discussion
1

Hi all,
I am having beaglebone black reference board. Instead of using the builtin wifi that comes with the kit, I would like to use a wifi module. That module has an SDIO interface. The wifi module kit has connected with the board(SDIO and MMC1 pins) . I have to configure the MMC pin headers as SDIO interface devices in the device tree file. Could, you please tell me how to add SDIO to the device tree.

Thanks in advance,
sankari.

Hi @sankari the “BeagleBone Green Wireless” used SDIO pins from mmc3 on the 2 external extension headers:

thanks, @RobertCNelson . So, Shall I take that mmc3 as a reference for my configuration?
