The vendor driver allows setting baud-rates higher than 115200 baud. There is a check in the vendor driver which prevents using more than 115200 baud during startup, however it does not have such a check in .set_termios. Higher baud-rates are often used by the bluetooth modules embedded into the SDIO wifi chips (Amlogic devices use brcmfmac based wifi chips quite often, 2000000 baud seems to be a common value for the UART baud-rate in Amlogic's "libbt"). I have tested this on a Meson GXL device with uart_A (to which the bluetooth module is connected, where initialization times out with 115200 baud) and uart_AO (which I manually set to 2000000 baud and then connected with my USB UART adapter to that).
