Hi Stefan, > The RPi 4 uses the hardware handshake lines for CYW43455, but the chip > doesn't react to HCI requests during DT probe. The reason is the inproper > handling of the RTS line during startup. According to the startup > signaling sequence in the CYW43455 datasheet, the hosts RTS line must > be driven after BT_REG_ON and BT_HOST_WAKE. > > Signed-off-by: Stefan Wahren <wahrenst@xxxxxxx> > --- > drivers/bluetooth/hci_bcm.c | 2 ++ > 1 file changed, 2 insertions(+) patch has been applied to bluetooth-next tree.
