I'm making some more progress. When I boot up now, the wl18xx on the SDIO interface is detected and enumerated:
mmc0: queuing unknown CIS tuple 0x91 (3 bytes)
mmc0: new high speed SDIO card at address 0001

I'm pretty sure this means the WLAN_IRQ I setup is not working. When I look in /proc/interrupts I see that the SDIO interface has had quite a few interrupts but the wl18xx has 0!

I think I misconfigured the interrupt. I am trying to use P7_1 ( GPIO 98 ). In the board-rskrza1.c, I've configured it like this:

struct wl12xx_platform_data custom_board_wlan_data __initdata = {
.irq = 98,
};
r7s72100_pfc_pin_assign(98, PMODE, DIR_IN);
pr_info("WILINK8 WLAN: Setting up wl12xx platform data\n");
if (wl12xx_set_platform_data(&custom_board_wlan_data))
pr_info("WILINK8 WLAN: Error setting up wl12xx platform data\n");
Am I setting up the IRQ correctly in the board file for the RZ/A1? Thank you.
