That part seems safe to me now. > --- a/drivers/tty/serial/8250/8250_omap.c > +++ b/drivers/tty/serial/8250/8250_omap.c ... > - const struct of_device_id *id; > - > - ret = of_alias_get_id(pdev->dev.of_node, "serial"); > - > - of_property_read_u32(pdev->dev.of_node, "clock-frequency", > - &up.port.uartclk); > - priv->wakeirq = irq_of_parse_and_map(pdev->dev.of_node, 1); > - > - id = of_match_device(of_match_ptr(omap8250_dt_ids), &pdev->dev); > - if (id && id->data) > - priv->habit |= *(u8 *)id->data; But this part it seems we still need to keep around as we still have lots of clock-frequency references in the *.dtsi files. Or am I missing something? Regards Tony
