Some patches are needed, but they're all for Tegra-specific code to configure the pinmux, GPIO, etc. on the Tegra SoC in order to correctly communicate with the SDIO port, and to enable the controller. No patches are required to the brcmfmac driver. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
