Just checked on kernel.org and indeed it is not in linux-2.6.36.2 (stable), but it is in 2.6.37-rc6 (main-line). Gr.

There a arch/arm/mach-imx directory containing i.MX27 processor which has some similarities (same core and MMC/SD interfaces). So it could be a good starting point for your porting effort. Another hint may be that SDIO is related to MMC/SD. So in board-zoom-peripherals.c you will find more when searching for 'mmc'. eg: static struct omap2_hsmmc_info mmc[] __initdata = { : : { .name = "wl1271", .mmc = 3, .caps = MMC_CAP_4_BIT_DATA, .gpio_wp = -EINVAL, .gpio_cd = -EINVAL, .nonremovable = true, }, {} /* Terminator */ }; Gr.

Luca suggested that I send this to all of you! I looked at arch/arm/mach-omap2/board-zoom-peripherals.c file.. I didn't see anything specific to SDIO.. I was looking at linux-2.6.36.2.. Is this the correct version to look at? Please read below for original question. THANK you everyone for ANY help you can give me!

Well, the wl12xx driver should work more or less out-of-the-box. The only thing you need to do is to set up the SDIO connection to your card (assuming that you're using the SDIO bus to connect it). I'm not familiar with the iMX233, but with OMAP, it's pretty simple. You can see the arch/arm/mach-omap2/board-zoom-peripherals.c file in the Linux kernel for an example on how to set it up for the Zoom board (OMAP-based). -- Cheers, Luca.
