Integrating wl1271 to android on beagleboard

Hi All,

  I am trying to integrate WL1271 to android on beagleboard xM through sdio, and

i did the following addition to the board specific information in board-omap3beagle.c

+#include <linux/regulator/fixed.h>
#include <linux/wl12xx.h>

#define OMAP_BEAGLE_WLAN_EN_GPIO (139)
#define OMAP_BEAGLE_BT_EN_GPIO (138)
#define OMAP_BEAGLE_WLAN_IRQ_GPIO (137)
#define OMAP_BEAGLE_FM_EN_BT_WU (136)

static void __init omap3_beagle_init(void)
 #endif

 

 

And I m getting the following errors

I) defined voltage range is below the required voltage, these wiil be ingored

II) error no:110- time out

 

Any information regarding to this will be helpful.

 

Thanks in advance,
