Because litex serial has fixed baudrate the callback only checks if the requested baudrate is the same as the CONFIG_BAUDRATE. --- drivers/serial/serial_litex.c | 9 ++++++++- 1 file changed, 8 insertions(+), 1 deletion(-) diff --git a/drivers/serial/serial_litex.c b/drivers/serial/serial_litex.c index 8562a45ecc..9d35a6e44a 100644 --- a/drivers/serial/serial_litex.c +++ b/drivers/serial/serial_litex.c @@ -58,6 +58,13 @@ static int litex_serial_tstc(struct console_device *cdev) return !litex_serial_readb(cdev, UART_RXEMPTY); } +static int litex_setial_setbaudrate(struct console_device *cdev, int baudrate) +{ + if (baudrate != CONFIG_BAUDRATE) + return -EINVAL; + return 0; +} + static int litex_serial_probe(struct device_d *dev) { struct resource *iores; @@ -73,7 +80,7 @@ static int litex_serial_probe(struct device_d *dev) cdev->tstc = &litex_serial_tstc; cdev->putc = &litex_serial_putc; cdev->getc = &litex_serial_getc; - cdev->setbrg = NULL; + cdev->setbrg = &litex_setial_setbaudrate; console_register(cdev); -- 2.31.1 _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox
