What's the mechanism by which wl12xx is bound with above. I see above wl12xx_set_platform_data but I didn't see something like .name = "wl1271" or dev_name that comes in through platform_device_register. If I look at other board files, I see: 321 #ifdef CONFIG_WL12XX_PLATFORM_DATA 322 { 323 .name = "wl1271", 324 .mmc = 2, 325 .caps = MMC_CAP_4_BIT_DATA | MMC_CAP_POWER_OFF_CARD, 326 .gpio_wp = -EINVAL, 327 .gpio_cd = -EINVAL, 328 .nonremovable = true, 329 }, 330 #endif and 729 #ifdef CONFIG_WL12XX_PLATFORM_DATA 730 /* WL12xx WLAN Init */ 731 if (wl12xx_set_platform_data(&omap3evm_wlan_data)) 732 pr_err("error setting wl12xx data\n"); 733 platform_device_register(&omap3evm_wlan_regulator); 734 #endif Thanks, jayakumar -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
