Subject: [PATCH] Bluetooth: hci_bcm: Default to 4 Mbps
Date: Sat, 29 Aug 2026 12:02:05 +0200 [thread overview]
Message-ID: <20260829100205.113655-1-paul@crapouillou.net> (raw)
The ACPI path already did default to 4000000 baud, while the OF path did
not, for some reason. This meant that unless overridden with the
'max-speed' OF property, the serial port would stay at the init speed of
115200 bps, making it unsuitable with high-speed Bluetooth devices like
audio equipment.
