config BT_HCI_SET_PUBLIC_ADDR
	bool
	select BT_HCI_SETUP
	help
	  Pass the controller's public address to the HCI driver in setup()

	  This option should be enabled by drivers for controllers that support setting the
	  public identity through vendor-specific commands. They can then implement the
	  setup() HCI driver API function and get the address to set from the public_addr field.

	  From the application side, the public address is set using the first call to
	  bt_id_create(), before calling bt_enable().

config BT_HCI_SETUP
	bool
	help
	  Enable the HCI vendor-specific Setup function.

	  This option has to be enabled when the BT Controller requires execution
	  of the vendor-specific commands sequence to initialize the BT Controller
	  before the BT Host executes a Reset sequence.

	  The user should generally avoid changing it via menuconfig or in
	  configuration files. This option are enabled by the vendor-specific
	  HCI extension, where the Setup function is implemented.
