Does that mean the low speed devices will stop working? It looks like this should be dynamically configurable based on what device is connected to it, no? > quot = s3c24xx_serial_getclk(ourport, baud, &clk, &clk_sel); > if (baud == 38400 && (port->flags & UPF_SPD_MASK) == UPF_SPD_CUST) > quot = port->custom_divisor; -- Lee Jones [李琼斯] Linaro Services Technical Lead Linaro.org │ Open source software for ARM SoCs Follow Linaro: Facebook | Twitter | Blog
