'''Disable TWL4030 PCM voice interface:'''
Default kernel has disabled TWL4030 PCM voice interface output pins to high impedance, otherwise this module forces the level of mcbsp3_fsx (uart2_rx) and mcbsp3_clkx (uart2_tx) pins. To make sure, go to [http://git.igep.es/?p=pub/scm/linux-omap-2.6.git;a=blob_plain;f=sound/soc/codecs/twl4030.c;hb=linux-2.6.35.y $(kernel path)/sound/soc/codecs/twl4030.c] file already read: <br>

"igep00x0_wifi_bt_init" function initializes WIFI and Bluetooth peripherals. "opt" variable Reset is used for reset (opt!=10) or not (opt==0) Bluetooth. For example you can disable Bluethoot Bluetooth editing these next lines:
