    pch_uart: Add user_uartclk parameter · 2a44feb2
    Darren Hart 提交于
    For cases where boards with non-default clocks are not yet added to the kernel
    or when the clock varies across hardware revisions, it is useful to be
    able to specify the UART clock on the kernel command line.
    
    Add the user_uartclk parameter and prefer it, if set, to the default and
    board specific UART clock settings. Specify user_uartclock on the command-line
    with "pch_uart.user_uartclk=48000000".
