    ARM: SAMSUNG: serial: Fix on handling of one clock source for UART · 470f2297
    Boojin Kim authored
    This patch fixes the way of comparison for handling of two or more
    clock sources for UART.
    
    For example, if just only one clock source is defined even though
    there are two clock sources for UART, the serial driver does not
    set proper clock up. Of course, it is problem.
    
    So this patch changes the condition of comparison to avoid useless
    setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
    selection of source clock is not required.
    
    In addition, since the Exynos4210 has only one clock source for UART
    this patch adds the flag into its common_init_uarts().
