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?

I think that EXT is only used by FM radio and not by bluetooth.

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. -- Sebastian > Signed-off-by: Tony Lindgren <tony@xxxxxxxxxxx> > --- > arch/arm/configs/omap2plus_defconfig | 3 +++ > 1 file changed, 3 insertions(+) > > diff --git a/arch/arm/configs/omap2plus_defconfig b/arch/arm/configs/omap2plus_defconfig > --- a/arch/arm/configs/omap2plus_defconfig > +++ b/arch/arm/configs/omap2plus_defconfig > @@ -126,6 +126,7 @@ CONFIG_AF_RXRPC=m > CONFIG_RXKAD=y > CONFIG_CFG80211=m > CONFIG_MAC80211=m > +CONFIG_RFKILL=m > CONFIG_DEVTMPFS=y > CONFIG_DEVTMPFS_MOUNT=y > CONFIG_DMA_CMA=y > @@ -343,12 +344,14 @@ CONFIG_IR_GPIO_TX=m > CONFIG_IR_PWM_TX=m > CONFIG_MEDIA_SUPPORT=m > CONFIG_MEDIA_CAMERA_SUPPORT=y > +CONFIG_MEDIA_RADIO_SUPPORT=y > CONFIG_MEDIA_CEC_SUPPORT=y > CONFIG_MEDIA_CONTROLLER=y > CONFIG_VIDEO_V4L2_SUBDEV_API=y > CONFIG_V4L_PLATFORM_DRIVERS=y > CONFIG_VIDEO_OMAP3=m > CONFIG_CEC_PLATFORM_DRIVERS=y > +CONFIG_RADIO_WL128X=m > # CONFIG_MEDIA_SUBDRV_AUTOSELECT is not set > CONFIG_VIDEO_TVP5150=m > CONFIG_DRM=m > -- > 2.19.2
