when rtk(also some others) wifi/bt combo chips suspend, it disconnect from bt-remote control unit(RCU). when RCU's powerkey pressed, it will send ble broadcast to rtk bt chip. As the rtk chips receive the broadcast, it should wake up the host, but it can't send bt-hid powerkey to host because it had lost communication with host. So,it just send a IRQ pulse to host. The host should resume from suspend. Because the RCU just send a IRQ pulse, so rk chips just resume by IRQ and then go to sleep again for no power-key event. this is not expected. we expect to power up system wholly. With this path, we try to power up the system. so we add a power-up key event when BT IRQ received. We also can control the "/proc/bluetooth/sleep/powerupkey" node to enable or disable this function.

Say Y here if you want to have control over RF switches

found on many WiFi and Bluetooth cards.

To compile this driver as a module, choose M here: the

module will be called rfkill.

If you say yes here you get support of a generic gpio RFKILL

driver.
