MMC SDIO WIFI module Detection issue

Current system is successfully using SDIO based WIFI module with embedded Linux kernel 4.4.x. Recently we changed the wifi module from TI to RealTek. Somehow this new wifi module is not getting detected. It gives MMC error -22.

Work involves just helping with detection of the card. Linux kernel auto detects MMCs/SDIOs so not expecting any software development here.

This is mainly debugging activity with knowledge of MMC/SDIO interface or configuration.

You can use any platform to show MMC/SDIO detection with the module works.
