The new code has been tested on the Motorola Droid 4. For testing the audio
should be configured to route Ext to Speaker or Headphone. Then you need to
plug headphone, since its cable is used as antenna. For testing there is a
'radio' utility packages in Debian. When you start the utility you need to
specify a frequency, since initial get_frequency returns an error:

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.

I only did a few quick tests with 'radio' utility. I could scan
for stations and I could listen to some station. I suppose the
wl128x-radio driver has some buggy code paths, but that are
unrelated to this patchset.

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?

For FM radio it's directly wired to EXT with no DAI being required.
I think that EXT is only used by FM radio and not by bluetooth. BT
seems to use TDM.

Merry Christmas!

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.

Mh. I suppose I forgot to add alias to support autoloading the
FM module.

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

fm_rx_ch8_1283.2.bts
fmc_ch8_1283.2.bts

There is also a TX firmware. The Droid 4's chip should support this,
but I don't know if there is audio routing for this feature.
