I have never heard of wl1270 while working at TI.  My only guess is that
this is a chip based on wl1271 (since the Murata specs only say b/g/n
and no "a" which is the 5GHz support in wl1273).  Maybe it's a cheaper
chip without Bluetooth? To be sure, you should ask TI.

Same as above... If this wl1270 is indeed based on the wl1271, it should
probably work.  With the driver you may need to add some new SDIO IDs
for it to be recognized though.
