Subject: [PATCH v3 1/2] dt-bindings: net: broadcom-bluetooth: Add property for autobaud mode
Date: Mon, 30 May 2022 17:02:17 +0200 [thread overview]
Message-ID: <f395ffd03a6594ee11975b708721a33ccf8a4871.1653916330.git.hakan.jansson@infineon.com> (raw)
In-Reply-To: <cover.1653916330.git.hakan.jansson@infineon.com>
Add property, "brcm,requires-autobaud-mode", to enable autobaud mode
selection.
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.
