* struct bcm_device - device driver resources
* @serdev_hu: HCI UART controller struct
* @list: bcm_device_list node
* @dev: physical UART slave
* @name: device name logged by bt_dev_*() functions
* @device_wakeup: BT_WAKE pin,
* assert = Bluetooth device must wake up or remain awake,
* deassert = Bluetooth device may sleep when sleep criteria are met
* @shutdown: BT_REG_ON pin,
* power up or power down Bluetooth device internal regulators
* @clk: clock used by Bluetooth device
* @clk_enabled: whether @clk is prepared and enabled
* @init_speed: default baudrate of Bluetooth device;
* the host UART is initially set to this baudrate so that
* it can configure the Bluetooth device for @oper_speed
* @oper_speed: preferred baudrate of Bluetooth device;
* set to 0 if @init_speed is already the preferred baudrate
* @irq: interrupt triggered by HOST_WAKE_BT pin
* @irq_active_low: whether @irq is active low
* @hu: pointer to HCI UART controller struct,
* used to disable flow control during runtime suspend and system sleep
* @is_suspended: whether flow control is currently disabled
