hi Albin,

Any reason you're not using the register access macro's like the rest
of the driver?

while (!(UART_GET_CSR(..) & ATMEL_US_RXRDY))

> +       return __raw_readl(aup->uart.membase + ATMEL_US_RHR);

return UART_GET_CHAR(..);

> +       __raw_writel(ch, aup->uart.membase + ATMEL_US_THR);

UART_PUT_CHAR(..., ch);


Otherwise the patch looks fine to me.

Regards,
  Andrew Victor
