Nice, good to see that ti-st kim stuff gone :) I gave this a quick
try using fmtools.git and fmscan works just fine. No luck yet with
fm though, it gives VIDIOC_G_CTRL: Not a tty error somehow so
maybe I'm missing some options, patch below for omap2plus_defconfig.

Hmm so looks like nothing to configure for the clocks or
CPCAP_BIT_ST_L_TIMESLOT bits for cap for the EXT? So the
wl12xx audio is wired directly to cpcap EXT then and not a
TDM slot on the mcbsp huh?

Same to you!

Subject: [PATCH] ARM: omap2plus_defconfig: Add RADIO_WL128X as a loadable
 module

This allows using the FM radio in the wl12xx chips after modprobe
fm_drv using radio from xawt, or fmtools.

Note that the firmware placed into /lib/firmware/ti-connectivity
directory:

fm_rx_ch8_1283.2.bts
fmc_ch8_1283.2.bts
