I'm trying to get the upcoming kernel 3.6 running. My biggest problem is wl1271 via SDIO. kernel 3.3.rc7 had no problems initializing and using WLAN. This way I configure WLAN interrupt and pass platform data:
/* WLAN */
omap_am3517evm_wlan_data.irq = gpio_to_irq(OMAP_AM3517EVM_WIFI_IRQ_GPIO);
if (wl12xx_set_platform_data(&omap_am3517evm_wlan_data))
pr_err("error setting wl12xx data\n");
during kernel boot I get a crash (see further). If I don't provide IRQ the system doesn't crash, but has no WLAN. It has something to to with making GPIO to IRQ or something similar. This is the kernel from https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git, the linux-omap shows the same behavior.
Uncompressing Linux... done, booting the kernel.
