wl1271 driver on Linux 3.10 for SabreSD

wl1271 driver on Linux 3.10 for SabreSD

[Hubert Chaumette]

Hi all,

I need to activate the wl12xx driver (from drivers/net/wireless/ti/) on a (Android) Linux 3.10.31 kernel on an i.MX6Q SabreSD board. The wl1271 is to communicate with the board through an SDIO interface (SD2 on the board).

I have built the driver modules (cfg80211 and mac80211; wlcore, wlcore_sdio and wl12xx), and insmod'ed them. They are listed by lsmod :
wlcore_sdio 3820 0 - Live 0x00000000
wl12xx 51103 0 - Live 0x00000000
wlcore 161008 1 wl12xx, Live 0x00000000
mac80211 253798 2 wl12xx,wlcore, Live 0x00000000
cfg80211 201451 2 wlcore,mac80211, Live 0x00000000

dmesg shows only a message from cfg80211 (no errors for other modules, when insmod'ed in the right order) :
cfg80211: Calling CRDA to update world regulatory domain

1) Can I use /sys/modules/{wlcore,wlcore_sdio,wl12xx}/ to test it ?
2) The board uses the device tree to enumerate platform devices. To correctly activate the driver, do I need to add it to the board DT (and a binding to the driver) ?
3) The driver is supposed to use a firmware (according to http://wireless.kernel.org/en/users/Drivers/wl12xx), how do I know whether it found it (no kernel log message) (I've put the firmware in /system/etc/firmware/) ?

Thanks in advance.
Regards,

Hubert
