Hi, This series (based von 4.8-rc1) adds support for bluetooth on the Nokia N9xx devices. It has been tested on the Nokia N950, where it works correctly. On Nokia N900 it currently fails during negotiation (probably related to slightly incorrect serial settings/timings). The N900's bcm2048 correctly answeres to alive check even before negotiation (on N950 it does not work before negotiation), but replies with an Hardware error event to the negotiation packet. Apart from N900 support there are still two "features" missing in the driver: 1. To save energy the bluetooth module can be put into sleep mode via a GPIO. This gpio should be enabled before sending data via UART and disabled once the transmission is done. I currently just keep the GPIO always enabled. 2. It would be nice to have a bluetooth device exposed by the kernel automatically without having to setup the tty disector first for proper configurationless out of the box support. I could not find a nice way to do this from the kernel, though. On N950 the driver works with omap-serial and omap8250-serial drivers.
