Add BCM43438 (bluetooth) as a slave device of uart0 (pl011/ttyAMA0). This allows to automatically insert the bcm43438 to the bluetooth subsystem instead of relying on userspace helpers (hciattach). Overwrite chosen/stdout-path to use 8250 aux uart as console. Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Loic Poulain <loic.poulain@gmail.com> Signed-off-by: Eric Anholt <eric@anholt.net>
