The TiWi 5 WiFi module needs special setup of the sdio interface before it can be probed. So far, this is done in omap_hsmmc_init_card() in omap_hsmmc.c which makes it useable only if connected to omap devices which use the omap_hsmmc. The OpenPandora is the most promient example. There are plans to switch to a newer sdhci-omap driver and retire omap_hsmmc. Hence this quirk must be reworked or moved somewhere else. Ideally to some location that is not dependent on the specific SoC mmc host driver. This is achieved by the new mmc_fixup_device() option introduced by ("mmc: allow to match the device tree to apply quirks") to match through device tree compatible string. This is called early right after where host->ops->init_card() and omap_hsmmc_init_card() was previously called. Signed-off-by: H.
