Rob, do you have a > plans for supporting the extra resources? I don't think the h/w I have can do FM or GPS. At least there's no headphone jack to serve as the FM antenna. For GPS, it seems support for that is not publicly available. Maybe an antenna is not needed to get the control interface working. It would be nice to integrate though and then we can kill off the shared transport driver. Marcel had mentioned that the Intel BT driver provides a regmap interface to its FM driver. Not sure if that would work for TI.
