/**

 * 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
