Subject: [PATCH] ARM: dts: Limit BT modem baud rate on 3B
|
|
|
|
The 3B doesn't have the flow control signals connected to the BT modem,
|
|
which limits the maximum usable baud rate to below 1 Mbaud. Use
|
|
921600 as a relatively safe default value, but the krnbt_baudrate
|
|
parameter can still override it.
