At that time, I want to describe that wlan and bluetooth were from the module named BCM43438. But, it's true that wlan do not be metioned in the code. I will update it in next version.

You means the shutdown-gpios? I configure it in the bluetooth node, it can't be configure in rfkill node at the same time.

Yes, I try to configure bt_reset_pin, bt_wake_host_irq and  bt_wake_pin in pinctrl separately. Each of them works well. After I connected a BT device to Edge2, I input rfkill block 1, bluetooth function failed. Then I input rfkill unblock 1, it can rework. So at last I only configure the bt_reset_pin.
