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. Signed-off-by: Frédéric Danis <frederic.danis@collabora.com> --- This has been tested with 5.4 kernel only. Afaict there's no change in this driver which should be impacted by this commit in latest kernel. v1 -> v2: Move speed copy from hci_bcm driver to hci_ldisc to be more generic drivers/bluetooth/hci_ldisc.c | 3 +++ 1 file changed, 3 insertions(+)
