If the property is present, the device is started in autobaud mode by asserting RTS (BT_UART_CTS_N) prior to powering on the device. Also prevent the use of unsupported commands for devices started in autobaud mode. Only a limited subset of HCI commands are supported in autobaud mode. Some devices (e.g. CYW5557x) require autobaud mode to enable FW loading. Autobaud mode can also be required on some boards where the controller device is using a non-standard baud rate in normal mode when first powered on.

This allows the host to use a baudrate higher than "init speed" when loading FW in autobaud mode. The device specific max baudrate in autobaud mode for CYW55572 is set to 921600 bps. Devices without device specific max baudrate in autobaud mode will use init speed as before. If no device specific init speed has been specified, it will default to the bcm_proto default 115200 bps. The increased baud rate improves FW load time. The exact load time will depend on the specific system and FW being used. As a rough indication, the FW load time dropped from ~9s @ 115.2kbps to ~1.7s @ 921.6kbps in one test.
