Or is > it just that wl1271 and wl1270 share compatible ops? 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?

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. -- Luca.
