4 Subject: [PATCH] ARM: dts: Limit BT modem baud rate on 3B
6 The 3B doesn't have the flow control signals connected to the BT modem,
7 which limits the maximum usable baud rate to below 1 Mbaud. Use
8 921600 as a relatively safe default value, but the krnbt_baudrate
9 parameter can still override it.
