Another issue:
serial_omap_set_termios()
{
...
/* FIFOs and DMA Settings */
/* FCR can be changed only when the
* baud clock is not running
* DLL_REG and DLH_REG set to 0.
*/
serial_out(up, UART_LCR, UART_LCR_CONF_MODE_A);
serial_out(up, UART_DLL, 0);
serial_out(up, UART_DLM, 0);
serial_out(up, UART_LCR, 0);
...
serial_out(up, UART_FCR, up->fcr);
...
}
serial_omap_restore_context()
{
serial_out(up, UART_LCR, UART_LCR_CONF_MODE_B); /* Config B mode */
serial_out(up, UART_DLL, up->dll);
serial_out(up, UART_DLM, up->dlh);
serial_out(up, UART_LCR, 0x0); /* Operational mode */
serial_out(up, UART_IER, up->ier);
serial_out(up, UART_FCR, up->fcr);
}
Either the comment is wrong, or the code in serial_omap_restore_context()
is wrong; they can't both be right. Please can someone let me know which
is the right version so we can fix that inconsistency.
Thanks.
