[PATCH v2 0/2] Bluetooth: hci_bcm: Autobaud mode support

From: Hakan Jansson
Date: Fri May 20 2022 - 11:07:47 EST


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 when first powered on.

Only a limited subset of HCI commands are supported in autobaud mode.

These patches add a DT property, "brcm,uses-autobaud-mode", to control
autobaud mode selection.

Changes v1 -> v2:
- Modify description in binding document
