BT core driver should addtionally check LMP feature bit
"Erroneous Data Reporting" instead of quirk
HCI_QUIRK_BROKEN_ERR_DATA_REPORTING set by BT device driver to decide if
HCI commands HCI_Read|Write_Default_Erroneous_Data_Reporting are broken.
BLUETOOTH CORE SPECIFICATION Version 5.3 | Vol 2, Part C | page 587
This feature indicates whether the device is able to support the
Packet_Status_Flag and the HCI commands HCI_Write_Default_-
Erroneous_Data_Reporting and HCI_Read_Default_Erroneous_-
Data_Reporting.
the quirk was introduced by 'commit cde1a8a992 ("Bluetooth: btusb: Fix
and detect most of the Chinese Bluetooth controllers")' to mark HCI
commands HCI_Read|Write_Default_Erroneous_Data_Reporting broken by BT
device driver, but the reason why these two HCI commands are broken is
that feature "Erroneous Data Reporting" is not enabled by firmware, this
scenario is illustrated by below log of QCA controllers with USB I/F:

Add device specific data for max baudrate in autobaud mode. 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.

Use the presence of a DT property, "brcm,requires-autobaud-mode", to enable

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.
