From 0519376db710783ebc97f1c72a09424af0bc920a Mon Sep 17 00:00:00 2001 From: Frédéric Danis Date: Tue, 20 Aug 2024 16:17:16 +0200 Subject: Bluetooth: hci_ldisc: Use speed set by btattach as oper_speed MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Starting a BCM UART controller not defined as a platform device or a serdev with "btattach -B /dev/ttyS1 -P bcm -S 3000000" works fine but the serial port remains at the init_speed, i.e. 115200. The oper_speed is only set if a device is declared in ACPI, device tree or as a platform device. This commit copies the serial port speed fixed by hciattach to the oper_speed on line discipline opening.
