However, need to proceed next step. As I said before, internal clock(USB_48MHz) should be used than external clock(UART_CLK) as default setting. --Reasons - Users don't always use 1.8432MHz as UART_CLK. So, In case of using except 1.8432MHz, the user needs to change both pch_phub and pch_uart setting (It's bother things). - High baud rate can't be used more than 115Kbps I think there is no merit to use UART_CLK. ---Merit to use 192MHz - Users don't have to care both pch_phub and pch_uart clock setting. - High baud rate can be supported thanks, ROHM Co., Ltd. tomoya -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
