Re: [PATCH 0/4 V2] pch_uart: Cleanups, board quirks, and user uartclk parameter

[Tomoya MORINAGA]

Hi

Darren's patch series, I think OK.
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,
